| What is a '''Radiobutton'''?

|
<ul>
<li><blockquote>A '''Radiobutton''' is a button with two states.</blockquote></li>
<li><blockquote>They are intended to be mutually exclusive.</blockquote></li>
<li><blockquote>As a result, at any given time only one '''button''' is in a selected state.</blockquote></li></ul>
|-

Objects to calculate simple and compound interest

|
To calculate the interest, we need three '''Edit''' boxes to take user inputs.

<ul>
<li><blockquote>The first '''Edit box''' for principal amount.</blockquote></li>
<li><blockquote>The second '''Edit box''' for rate of interest.</blockquote></li>
<li><blockquote>The third '''Edit box''' for time.</blockquote></li></ul>

After that, we need two '''Radiobuttons''' to calculate Simple and Compound interest.

Lastly, one '''Text''' box is required to display the answer.
|-
|
Cursor on '''GUIBuilder''' Palette,

Hover over '''GUIBuilder''' Palette and '''Graphic window number 1.'''

Hover over three '''Edit''' boxes and one '''Text''' box
|
I have already opened the '''guiFigure.sce''' file using the '''GUIBuilder toolbox'''.

The '''GUIBuilder Palette''' and '''Graphic window number 1''' open up.

The graphic window shows the '''GUI''' with three '''Edit''' boxes and one '''Text''' box.
|-
|
Cursor on '''GUIBuilder Palette,'''

hover over the first '''Edit''' box.
| The first '''Edit''' box has the '''String''' ‘'''Enter principal amount’''' with '''Tag ‘ed_principal’.'''

|-
|
Cursor on '''GUIBuilder''' Palette,

hover over the second '''Edit''' box.
| The second '''Edit''' box has the '''String ‘Enter rate of interest’''' with '''Tag ‘ed_rate’.'''

|-
|
Cursor on '''GUIBuilder''' Palette,

hover over the third '''Edit''' box.
| The third '''Edit''' box has the '''String ‘Enter time’''' with '''Tag ‘ed_time’.'''

|-
|
Cursor on '''GUIBuilder''' Palette,

hover over the '''Text''' box.
| The '''Text''' box has the '''String ‘UnName4’''' with '''Tag ‘txt_answer’'''.

|-
|
Only narration
| Now l will add two '''Radiobuttons''' for Simple interest and Compound interest.
|-
|
On '''GUIBuilder Palette''',

click '''Radiobutton.'''
| Go to '''GUIBuilder Palette''' and click on '''Radiobutton'''.

|-
|
On '''Scilab Multiple Values Request''' window,

type '''rd_simple''' and type '''Simple interest.'''

Click on '''OK.'''
|
Let us type '''rd_simple''' as the '''Tag''' and '''Simple interest''' as the '''String'''.

Then click on '''OK'''.
|-
|
On '''Graphic window number 1,'''

place '''Radiobutton''' in the middle left.

Hover cursor over '''Simple''' '''interest''' '''Radiobutton'''.
|
Let us place this '''Radiobutton''' in the middle left of '''Graphic window number 1'''.

'''‘Simple interest’ Radiobutton''' appears.
|-
|
On '''GUIBuilder Palette''',

click '''Radiobutton.'''
| Let us take another '''Radiobutton''' for the Compound interest.

|-
|
On '''Scilab Multiple Values Request''' window,

type '''rd_compound''' and type '''Compound interest.'''

Click on '''OK.'''
|
Now I will type '''rd_compound''' as the '''Tag''' and ‘'''Compound interest’''' as the '''String'''.

Then click on '''OK'''.
|-
|
On '''Graphic window number 1,'''

place '''Radiobutton''' in the middle right.

Hover cursor over '''Radiobutton'''
|
Place this '''Radiobutton''' next to the '''Simple interest Radiobutton'''.

‘'''Compound interest’ Radiobutton''' appears.
|-
|

| Now the '''GUI''' part is completed.
|-
|
On '''GUIBuilder Palette''' window,

'''Generate>>Generate GUI code.'''
|
Let us save the file.

Go to the '''GUIBuilder Palette'''.

Click on '''Generate''' and then on the '''Generate GUI code'''.
|-
|
Save as '''interest-calculator'''.

Click on '''Save.'''
|
I will save this file as '''interest-calculator.'''

Click on '''Save'''.
|-
|
On '''GUI created window,'''

click on '''OK.'''
|
A pop up opens with a message “'''GUI created successfully'''.”

Click on '''OK'''.
|-
|
On '''SciNotes''' window,

highlight '''handles''' for '''principal, rate, time, simple interest, compound interest''' and '''answer'''.
|
You can see that the corresponding '''Scilab code''' has been generated.

Notice the '''handles''' and '''properties''' of the objects we took on a '''graphic window'''.

|-
| Highlight '''handles.ed_principal'''.
| '''handles.ed_principal''' is the '''handle''' for principal amount.
|-
| Highlight '''handles.ed_rate'''.
| '''handles.ed_rate''' is the '''handle''' for rate.
|-
| Highlight '''handles.ed_time'''.
| '''handles.ed_time''' is the '''handle''' for time.
|-
| Highlight '''handles.txt_answer'''.
| '''handles.txt_answer''' is the '''handle''' for answer'''.'''
|-
| Highlight '''handles.rd_simple'''.
| '''handles.rd_simple''' is the '''handle''' for simple interest.
|-
| Highlight '''handles.rd_compound'''.
| '''handles.rd_compound''' is the '''handle''' for compound interest.
|-
|
Hover cursor over '''rd_simple_callback'''

function.
| Now let us write a function definition for '''rd_simple_callback function'''.
|-
|
Cursor on '''SciNotes''' window,

type within '''rd_simple_callback'''.

'''handles.rd_simple.value = 1'''

'''handles.rd_compound.value = 0'''

'''Principal = strtod(handles.ed_principal.string)'''

'''Rate = strtod(handles.ed_rate.string)'''

'''Time = strtod(handles.ed_time.string)'''

'''SI = (Principal * Rate * Time)/100'''

'''handles.txt_answer.string = string(SI)'''
|
Enter the code as seen here with the same syntax.

The same code can be found under the code files section.

You can use it as explained earlier in this tutorial.

|-
|
Highlight,

'''handles.rd_simple.value = 1'''

'''handles.rd_compound.value = 0'''

|
After clicking the '''Simple interest Radiobutton-'''

<ul>
<li><blockquote>This line will select the '''Simple interest Radiobutton'''.</blockquote></li>
<li><blockquote>The following line will deselect the '''Compound interest''' '''Radiobutton'''.</blockquote></li></ul>

This way only one button remains selected.
|-
|
Highlight,

'''Principal = strtod(handles.ed_principal.string)'''
| Next line then assigns the user input for principal value to variable '''‘Principal’'''.
|-
|
Highlight,

'''Rate = strtod(handles.ed_rate.string)'''
| Its next line assigns the user input for rate of interest to variable '''‘Rate’'''.
|-
|
Highlight,

'''Time = strtod(handles.ed_time.string)'''
| The further line assigns the user input for time to the variable '''‘Time’'''.
|-
|
Highlight,

'''SI = (Principal * Rate * Time)/100'''

|
Notice the next line.

This equation will perform the calculations.

The final result will be stored in the variable '''‘SI''''.
|-
|
Highlight,

'''handles.txt_answer.string = string(SI)'''
| The last line will give the value of the variable '''‘SI’''' to the '''Text''' box.
|-
| Hover cursor over '''rd_compound_callback''' function.
| Next I will write a function definition for '''rd_compound_callback''' function'''.'''
|-
|
Cursor on '''SciNotes''' window,

type within '''rd_compound_callback'''.

'''handles.rd_compound.value = 1'''

'''handles.rd_simple.value = 0'''

'''Principal = strtod(handles.ed_principal.string)'''

'''Rate = strtod(handles.ed_rate.string)'''

'''Time = strtod(handles.ed_time.string)'''

'''CI = (Principal *(1+( Rate/100))^ Time) - Principal'''

'''handles.txt_answer.string = string(CI)'''
|
Enter the code as seen here with the same syntax.

The same code can be found under the '''Code files''' section.

|-
|
Highlight,

'''handles.rd_compound.value = 1'''

'''handles.rd_simple.value = 0'''

|
This action is similar to what we have seen earlier.

After clicking the '''Compound interest''' '''Radiobutton-'''

<ul>
<li><blockquote>The first line will now select the '''Compound interest''' '''Radiobutton'''.</blockquote></li>
<li><blockquote>The next line will deselect the '''Simple interest Radiobutton'''.</blockquote></li></ul>
|-
|
Highlight,

'''Principal = strtod(handles.ed_principal.string)'''

'''Rate = strtod(handles.ed_rate.string)'''

'''Time = strtod(handles.ed_time.string)'''
| Notice the next three lines are the same as in the '''rd_simple_callback function.'''

|-
|
Highlight,

'''CI = (Principal *(1+( Rate/100))^ Time) - Principal'''
|
The next line will calculate the Compound interest.

The final result will be stored in variable '''‘CI'.'''
|-
|
Highlight,

'''handles.txt_answer.string = string(CI)'''
| The last line will give the value of variable '''‘CI’''' to the '''Text''' box.
|-
| Press '''Ctrl+S.'''
| Let us save the '''Scilab code''' by pressing '''Ctrl''' and '''S''' keys together.
|-
|
On '''Scinotes''' window,

'''Execute'''>>'''file''' '''with echo'''
|
Execute this by clicking '''Execute''' on the '''menubar''' and then on '''File with echo'''.

'''Graphic window number 2''' opens.
|-
|
On '''Graphic window number 2,'''

delete '''Enter the principal amount here. '''

Type '''8000.'''

Delete '''Enter rate of interest.'''

Type '''7'''.

Delete '''Enter time.'''

Type '''3'''.
|
Now let us test the '''GUI.'''

Delete the '''string “Enter principal amount”''' from the '''Edit''' box and type '''8000'''.

Delete the '''string “Enter rate of interest”''' from the '''Edit''' box and type '''7'''.

Delete the '''string “Enter time”''' from the '''Edit''' box and type '''3'''.
|-
|
On '''Graphic window number 1,'''

click on '''Simple interest radiobutton'''.

Hover cursor over '''Text''' box.
|
Then click on the '''Simple''' '''interest''' '''Radiobutton.'''

The '''Text''' box shows the desired answer of '''1680''' as expected.
|-
|
On '''Graphic window number 1,'''

click on '''Compound interest radiobutton'''.

Hover cursor over '''Text''' box.
|
Next click on the '''Compound''' '''interest''' '''Radiobutton.'''

Now the '''Text''' box shows the desired answer of '''1800.344''' as expected.

'''What is Checkbox?'''
|
A '''Checkbox''' is a button with two states.

It is used when a user wants to make multiple independent choices.
|-
|
Cursor on '''GUIBuilder Palette''' and '''Graphic window number 1'''

|
Let us begin with creating the '''GUI'''.

I have opened the '''GUIBuilder toolbox'''.
|-
|
Cursor on '''GUIBuilder Palette''',

click '''Checkbox.'''
| Go to '''GUIBuilder''' '''Palette''' and click on '''Checkbox'''.
|-
|
On '''Scilab Multiple Values Request''' window,

type '''chk_sine''' as '''Tag''',

type '''sin(t)''' as '''String.'''

Click on '''OK.'''
|
Type '''chk_sine''' as the '''Tag''' and '''sin(t)''' as the '''String'''.

Then click on '''OK'''.
|-
|
On '''Graphic window number 1,'''

place the '''Checkbox''' in the window's top left side.

Hover cursor over '''Checkbox'''.
|
Place the '''Checkbox''' in the window's top left side by considering a suitable size.

A '''sin(t) Checkbox''' appears.
|-
|
On '''GUIBuilder Palette''',

hover over '''cos(t) Checkbox.'''

|
In the similar way, I have taken another '''Checkbox''' for the '''cosine function'''.

I have written '''chk_cosine''' as the '''Tag''' and '''cos(t)''' as the '''String'''.

By considering the suitable size, I have placed it below the '''sin(t) Checkbox'''.

Pause the tutorial and do likewise in your '''GUI''' interface.
|-
| On '''GUIBuilder Palette''',
| To display the response of a system, we need '''Axes'''.
|-
|
On '''Graphic window number 1,'''

hover over '''Axes'''.

|
Hence I have taken an '''Axes''' with '''ax_response''' as '''Tag''' and '''System Response''' as '''String'''.

Notice that I have placed it on the right side of the window.

It appears like a box with a black border.

Again, pause the tutorial and do likewise in your '''GUI''' interface.
|-
|

| Now the '''GUI''' part is completed.
|-
|
On '''GUIBuilder Palette''' window,

'''Generate>>Generate GUI code.'''
|
Let us generate the '''Scilab code''' file for this.

Go to the '''GUIBuilder Palette'''.

Click on '''Generate''' and then on the '''Generate GUI code.'''
|-
|
Save as '''finding_wave'''.

Click on '''Save.'''
|
I will save this file as '''finding_wave.'''

Click on '''Save'''.
|-
|
On '''GUI created window,'''

Click on '''OK.'''
|
A pop up opens with the message “'''GUI created successfully'''.”

Click on '''OK.'''
|-
|
On '''SciNotes''' window,

highlight '''handles''' for '''sine''', '''cosine''' and '''axes'''.
|
You can see that the corresponding '''Scilab code''' has been generated.

Notice the '''handles''' and '''properties''' of the objects we took on a '''graphic window'''.
|-
| Highlight '''handles.chk_sine'''.
| '''handles.chk_sine''' is the '''handle''' for '''sine Checkbox.'''
|-
| Highlight '''handles.chk_cosine'''.
| '''handles.chk_cosine''' is the '''handle''' for '''cosine Checkbox.'''
|-
| Highlight '''handles.ax_response'''.
| '''handles.ax_response''' is the '''handle''' for '''Axes.'''
|-
| Hover cursor over '''chk_sine_callback''' function.
| Now let us write a function definition within the '''chk_sine_callback function'''.
|-
|
Cursor on '''SciNotes''' window,

type within '''chk_sine_callback'''.

Type,

'''t = 0:0.1:2*%pi;'''

'''if handles.chk_sine.Value == 1'''

'''then plot(t,sin(t))'''

'''else'''

'''plot(t,sin(t),'w')'''

'''end'''
|
Enter the code as seen here with the same syntax.

The same code can be found under the '''Code files''' section.

You can use it as explained earlier in this tutorial.

|-
|
Highlight,

'''t = 0:0.1:2*%pi;'''
| The first line defines the range of '''t''' from '''0''' to '''2 pi''' with a step size of '''0.1'''.
|-
|
Highlight,

'''if handles.chk_sine.Value == 1'''

'''then plot(t,sin(t))'''

'''else'''

'''plot(t,sin(t),'w')'''

'''end'''
|
Further an '''if else''' statement is defined.

The '''checkbox''' for '''sin(t)''' is checked if the value is set to 1.

So, if it is checked then the response of the '''sine''' wave is plotted.

If it is unchecked, then an invisible response will be plotted with white color.

|-
|
Cursor on '''SciNotes''' window,

type within '''chk_cosine_callback'''.

Type,

'''t = 0:0.1:2*%pi;'''

'''if handles.chk_cosine.Value == 1'''

'''then plot(t,cos(t))'''

'''else'''

'''plot(t,cos(t),'w')'''

'''end'''
|
Next I will write a function definition for '''chk_cosine_callback function.'''

Enter the code as seen here with the same syntax as explained earlier.

The same code can also be found under the '''Code files''' section.

|-
|
Highlight,

'''t = 0:0.1:2*%pi;'''
|
The first line is the same as seen in the '''chk_sine_callback function.'''

It will define the range of '''‘t’'''.
|-
|
Highlight,

'''if handles.chk_cosine.Value == 1'''

'''then plot(t,cos(t))'''

'''else'''

'''plot(t,cos(t),'w')'''

'''end'''
|
Further an '''if else''' statement for '''cos(t) checkbox''' is defined.

This action is similar to what we have seen previously.

If the '''checkbox''' for '''cos(t)''' is checked, then it will plot the response of the '''cosine''' wave.

If it is unchecked, then an invisible response will be plotted with white color.

|-
| Press '''Ctrl+S.'''
| Now let us save the '''Scilab code''' by pressing '''Ctrl''' and '''S''' keys together.
|-
|
On '''Scinotes''' window,

'''Execute'''>>'''file''' '''with echo.'''
| To execute, click on '''Execute''' on the '''menu bar''' and then on '''file with echo'''.

|-
|
On '''Graphic window number 2,'''

check the '''sin(t) checkbox.'''

Hover cursor over the '''Axes'''.
|
Now check the '''sin(t) checkbox.'''

You will see the time response of the '''sine function''' on the '''Axes'''.
|-
|
On '''Graphic window number 2,'''

check the '''cos(t) checkbox.'''

Hover cursor over the '''Axes'''.
|
Let us now check the '''cos(t)''' '''checkbox'''.

'''Axes''' shows the time response of the '''cosine function''' along with the '''sine''' '''function'''.
|-
|
On '''Graphic window number 2,'''

uncheck the '''sin(t) checkbox'''

check the '''sin(t) checkbox.'''

|
Now uncheck the '''sin(t)''' '''checkbox.'''

The response of '''sine''' function is not visible now.

If we check the '''sin(t)''' '''checkbox''' then the '''sine function''' response is again visible.

This way we can perform the basic plotting using '''GUI.'''

|
We can see that the corresponding '''Scilab code''' has been generated.

Notice the '''handles''' and '''properties''' of the objects we took on a '''graphic window'''.
|-
| Highlight '''handles.ed_base'''.
| '''handles dot ed underscore base''' is the '''handle''' for base.
|-
| Highlight '''handles.ed_exponent'''.
| '''handles dot ed underscore exponent''' is the '''handle''' for exponent.
|-
| Highlight '''handles.txt_output.'''.
| '''handles dot txt underscore output''' is the '''handle''' for output.
|-
| Highlight '''handles.pb_cal.'''
| '''handles dot pb underscore cal''' is the '''handle''' for '''Pushbutton.'''
|-
| Hover cursor over '''pb_cal_callback''' function.
| Now let us write a function definition for '''pb_cal_callback function'''.
|-
|
Cursor on '''SciNotes''' window,

type within '''pb_cal_callback'''.

Type,

'''base = strtod(handles.ed_base.string)'''

'''exponent = strtod(handles.ed_exponent.string)'''

'''out = base^exponent'''

'''handles.txt_output.string = string(out)'''
|
Enter the code as seen here with the same syntax.

The same code can be found under the '''Code files''' section.

You can use it as explained earlier in this tutorial.

|-
|
Highlight,

'''base = strtod(handles.ed_base.string)'''
| The first line assigns the user input for a base value to the variable ‘base’.
|-
|
Highlight,

'''exponent = strtod(handles.ed_exponent.string)'''
| The second line assigns the user input for an exponent to the variable ‘exponent’.
|-
|
On '''SciNotes''' window,

within '''pb_cal_callback.'''

highlight '''strtod''' command.
|
It is not possible to do calculations when the value is in '''string''' format.

Hence I have put the '''handles''' inside the '''strtod''' command.

This command will convert the value from the '''string''' format to a decimal format.
|-
|
Highlight,

'''out = base^exponent'''
|
Notice the next line.

This equation will perform the calculations.

The final result will be stored in the variable ‘out’.
|-
|
Highlight,

'''handles.txt_output.string = string(out)'''
| The last line will give the value of a variable ‘out’ to the '''Text box'''.
|-
| Press '''Ctrl+S.'''
| Let us save all our work by pressing '''Control''' and '''S''' keys together.
|-
|
On '''Scinotes''' window,

'''Execute'''>>'''file''' '''with echo'''
|
Execute this by clicking '''Execute''' on the '''menubar''' and then on '''File with echo'''.

The '''Graphic window number 2''' opens.
|-
|
On '''Graphic window number 2,'''

delete '''Enter the base. '''

Type '''4.'''

Delete '''Enter an exponent.'''

Type '''2'''.
|
Now let us test the '''GUI.'''

I will calculate '''4''' to the '''power 2'''.

Delete the '''string “Enter the base”''' from the '''Edit box''' and type '''4'''.

Delete the '''string “Enter an exponent”''' from the '''Edit box''' and type '''2'''.

|-
|
On '''Graphic window number 2,'''

click on '''Calculate Pushbutton'''.

Hover cursor over '''Text''' box.
|
Then click on the '''Calculate Pushbutton.'''

The '''Text box''' shows the desired answer of '''16''' as we expected.

This way we can perform numeric calculations using '''GUI''' in '''Scilab'''.

type within '''pb_cal_callback'''.

Type,

'''base = strtod(handles.ed_base.string)'''

'''exponent = strtod(handles.ed_exponent.string)'''

'''out = base^exponent'''

'''handles.txt_output.string = string(out)'''
|
Enter the code as seen here with the same syntax.

The same code can be found under the '''Code files''' section.

You can use it as explained earlier in this tutorial.

|-
|
Highlight,

'''base = strtod(handles.ed_base.string)'''
| The first line assigns the user input for a '''base''' value to the '''variable ‘base’'''.
|-
|
Highlight,

'''exponent = strtod(handles.ed_exponent.string)'''
| The second line assigns the user input for an '''exponent''' to the '''variable ‘exponent’'''.
|-
|
On '''SciNotes''' window,

within '''pb_cal_callback.'''

highlight '''strtod''' command.
|
It is not possible to do calculations when the value is in '''string''' format.

Hence I have put the '''handles''' inside the '''strtod command.'''

This '''command''' will convert the value from the '''string''' format to a '''decimal''' format.
|-
|
Highlight,

'''out = base^exponent'''
|
Notice the next line.

This equation will perform the calculations.

The final result will be stored in the '''variable ‘out.''''
|-
|
Highlight,

'''handles.txt_output.string = string(out)'''
| The last line will give the value of a '''variable ‘out’''' to the '''Text box'''.
|-
| Press '''Ctrl+S.'''
| Let us save all our work by pressing '''Control''' and '''S''' keys together.
|-
|
On '''Scinotes''' window,

'''Execute'''>>'''file''' '''with echo'''

'''Execute''' this by clicking '''Execute''' on the '''menubar''' and then on '''File with echo'''.

The '''Graphic window number 2''' opens.
|-
|
On '''Graphic window number 2,'''

delete '''Enter the base. '''

Type '''4.'''

Delete '''Enter an exponent.'''

Type '''2'''.
|
Now let us test the '''GUI.'''

I will calculate '''4''' to the '''power 2'''.

Delete the '''string “Enter the base”''' from the '''Edit box''' and type '''4'''.

Delete the '''string “Enter an exponent”''' from the '''Edit box''' and type '''2'''.

|-
|
On '''Graphic window number 2,'''

click on '''Calculate Pushbutton'''.

Hover cursor over '''Text''' box.
|
Then click on the '''Calculate Pushbutton.'''

The '''Text box''' shows the desired answer of '''16''' as we expected.

This way we can perform numeric calculations using '''GUI''' in '''Scilab'''.

On '''SciNotes''' window,

highlight '''handles''' for '''base, exponent output''' and '''Calculate'''.
|
We can see that the corresponding '''Scilab code''' has been generated.

Notice the '''handles''' and '''properties''' of the objects we took on a '''graphic window'''.
|-
| Highlight '''handles.ed_base'''.
| '''handles dot ed underscore base''' is the '''handle''' for '''base'''.
|-
| Highlight '''handles.ed_exponent'''.
| '''handles dot ed underscore exponent''' is the '''handle''' for '''exponent'''.
|-
| Highlight '''handles.txt_output.'''.

|
Highlight,

'''exponent = strtod(handles.ed_exponent.string)'''
| The second line assigns the user input for an '''exponent''' to the '''variable ‘exponent’'''.
|-
|
On '''SciNotes''' window,

within '''pb_cal_callback.'''

highlight '''strtod''' command.
|
It is not possible to do calculations when the value is in '''string''' format.

Hence I have put the '''handles''' inside the '''strtod command.'''

This '''command''' will convert the value from the '''string''' format to a '''decimal''' format.
|-
|
Highlight,

'''out = base^exponent'''
|
Notice the next line.

This equation will perform the calculations.

The final result will be stored in the '''variable ‘out.''''
|-
|
Highlight,

'''handles.txt_output.string = string(out)'''
| The last line will give the value of a '''variable ‘out’''' to the '''Text box'''.
|-
| Press '''Ctrl+S.'''

There are two ways to define '''variables''' in '''Xcos''':

<ul>
<li><blockquote>Defining variables from the '''Scilab Console.'''</blockquote></li>
<li><blockquote>Defining variables from the context '''menu.'''</blockquote></li></ul>
|-
|

| First we will create a simple '''simulation.'''
|-
|
Show slide:

'''Simulation - Blocks used'''

|
For this we used the below blocks

<ul>
<li><blockquote>'''RAMP'''</blockquote></li>
<li><blockquote>'''CLOCK underscore c''' and</blockquote></li>
<li><blockquote>'''CSCOPE'''</blockquote></li></ul>
|-
| Show '''Scilab workspace window'''

|
Open '''Scilab.'''

Type in '''‘xcos'''’ in the '''Scilab console''' and press '''enter.'''

Two windows will open :

<ul>
<li><blockquote>'''Palette browser''' and the</blockquote></li>
<li><blockquote>'''Untitled-Xcos window.'''</blockquote></li></ul>
|-
|
Show '''Xcos window'''

'''Sources palette>>RAMP block'''

|
To create the '''simulation''' we will have to import the necessary '''blocks.'''

<ul>
<li><blockquote>In the '''Palette browser-Xcos''' window, click on '''Sources''' palette.</blockquote></li>
<li><blockquote>In the right panel, select the '''RAMP''' block.</blockquote></li>
<li><blockquote>Now, drag and drop this block in the '''Untitled-Xcos''' window.</blockquote></li></ul>
|-
| '''Sinks palette>>CSCOPE block'''

|
<ul>
<li><blockquote>Go to the '''Palette browser-Xcos window'''.</blockquote></li>
<li><blockquote>Click on the '''sinks palette'''.</blockquote></li>
<li><blockquote>In the right panel, scroll down and select the '''CSCOPE''' block.</blockquote></li>
<li><blockquote>Drag and drop it next to the '''RAMP''' block in the '''Untitled-Xcos window'''</blockquote></li></ul>
|-
| '''Event handling>>Clock_c block'''

|
<ul>
<li><blockquote>Again go to the '''event handling palette''', select the '''CLOCK underscore c block.'''</blockquote></li>
<li><blockquote>Then drag and drop it above the '''CSCOPE block''' in the '''untitled -Xcos window'''</blockquote></li></ul>
|-
| Show '''Xcos window'''

|
Next we will interconnect all the '''blocks.'''

<ul>
<li><blockquote>Connect black '''output''' port of '''RAMP''' to black '''input''' port of '''CSCOPE.'''</blockquote></li>
<li><blockquote>Connect the red '''output''' port of '''CLOCK underscore c''' to the red '''input''' port of '''CSCOPE'''.</blockquote></li>
<li><blockquote>Our simulation is ready.</blockquote></li></ul>
|-
| Show '''Xcos window'''
|
<ul>
<li><blockquote>Then right click on the RAMP '''block''' and select the block '''parameters.'''</blockquote></li>
<li><blockquote>Here we set the '''slope parameter''' to '''‘a’''' and click '''OK''' .</blockquote></li>
<li><blockquote>It shows an error as '''‘a’''' is not defined.</blockquote></li>
<li><blockquote>This is correct because we never defined the '''variable ‘a’''' before.</blockquote></li></ul>
|-
| '''Show Scilab workspace window'''
|
Our first way to define a '''variable''' is using the '''Scilab console.'''

For this, go to the '''Scilab console''' .

Type '''‘a=1’''' and press '''enter'''
|-
| '''Show Xcos window'''
|
Now come back to the '''Untitled-Xcos window''' .

<ul>
<li><blockquote>Right click on the '''RAMP block''' and select the '''block parameter''' option in the menu.</blockquote></li>
<li><blockquote>Again we set the '''slope parameter''' to '''‘a’''' and click '''ok.'''</blockquote></li></ul>
|-
|

|
To start the '''simulation''', go to the toolbar of the '''Untitled-Xcos window'''.

Then click on the '''Start''' button that is of the shape of the play button.
|-
|

|
We will see a '''warning message''' saying that there is '''no continuous time state'''.

This can be ignored in this example. So click on '''OK.'''
|-
| '''Show graphic window'''
| Now, we can see that the '''slope''' of the output '''RAMP signal''' changes to '''a''' in the graphic window.
|-
|

|
Next we will see how to define variables

using the '''context menu''' in the '''Xcos toolbar.'''
|-
| Show '''workspace window'''

<blockquote>First we will have to clear the previous value of '''a'''. For this :
</blockquote>
<ul>
<li><blockquote>Go to the '''scilab console window'''</blockquote></li>
<li><blockquote>Type in '''‘clear a’''' in the '''console''' and press '''enter''' .</blockquote></li>
<li><blockquote>Now type '''‘a’''' and press Enter</blockquote></li>
<li><blockquote>We can see that the '''console''' shows ‘'''a’''' as undefined.</blockquote></li></ul>

To create the '''simulation''' we will have to import the necessary '''blocks.'''

<ul>
<li><blockquote>In the '''Palette browser-Xcos''' window, click on '''Sources''' palette.</blockquote></li>
<li><blockquote>In the right panel, select the '''RAMP''' block.</blockquote></li>
<li><blockquote>Now, drag and drop this block in the '''Untitled-Xcos''' window.</blockquote></li></ul>
|-
| '''Sinks palette>>CSCOPE block'''

|
<ul>
<li><blockquote>Go to the '''Palette browser-Xcos window'''.</blockquote></li>
<li><blockquote>Click on the '''sinks palette'''.</blockquote></li>
<li><blockquote>In the right panel, scroll down and select the '''CSCOPE''' block.</blockquote></li>
<li><blockquote>Drag and drop it next to the '''RAMP''' block in the '''Untitled-Xcos window'''</blockquote></li></ul>
|-
| '''Event handling>>Clock_c block'''

|
<ul>
<li><blockquote>Again go to the '''event handling palette''', select the '''CLOCK underscore c block.'''</blockquote></li>
<li><blockquote>Then drag and drop it above the '''CSCOPE block''' in the '''untitled -Xcos window'''</blockquote></li></ul>
|-
| Show '''Xcos window'''

|
Next we will interconnect all the '''blocks.'''

<ul>
<li><blockquote>Connect black '''output''' port of '''RAMP''' to black '''input''' port of '''CSCOPE.'''</blockquote></li>
<li><blockquote>Connect the red '''output''' port of '''CLOCK underscore c''' to the red '''input''' port of '''CSCOPE'''.</blockquote></li>
<li><blockquote>Our simulation is ready.</blockquote></li></ul>
|-
| Show '''Xcos window'''
|
<ul>
<li><blockquote>Then right click on the RAMP '''block''' and select the block '''parameters.'''</blockquote></li>
<li><blockquote>Here we set the '''slope parameter''' to '''‘a’''' and click '''OK''' .</blockquote></li>
<li><blockquote>It shows an error as '''‘a’''' is not defined.</blockquote></li>
<li><blockquote>This is correct because we never defined the '''variable ‘a’''' before.</blockquote></li></ul>
|-
| '''Show Scilab workspace window'''
|
Our first way to define a '''variable''' is using the '''Scilab console.'''

For this, go to the '''Scilab console''' .

Type '''‘a=1’''' and press '''enter'''
|-
| '''Show Xcos window'''
|
Now come back to the '''Untitled-Xcos window''' .

<ul>
<li><blockquote>Right click on the '''RAMP block''' and select the '''block parameter''' option in the menu.</blockquote></li>
<li><blockquote>Again we set the '''slope parameter''' to '''‘a’''' and click '''ok.'''</blockquote></li></ul>
|-
|

|
To start the '''simulation''', go to the toolbar of the '''Untitled-Xcos window'''.

Then click on the '''Start''' button that is of the shape of the play button.
|-
|

|
We will see a '''warning message''' saying that there is '''no continuous time state'''.

This can be ignored in this example. So click on '''OK.'''
|-
| '''Show graphic window'''
| Now, we can see that the '''slope''' of the output '''RAMP signal''' changes to '''a''' in the graphic window.
|-
|

|
Next we will see how to define variables

using the '''context menu''' in the '''Xcos toolbar.'''
|-
| Show '''workspace window'''
|
<blockquote>First we will have to clear the previous value of '''a'''. For this :
</blockquote>
<ul>
<li><blockquote>Go to the '''scilab console window'''</blockquote></li>
<li><blockquote>Type in '''‘clear a’''' in the '''console''' and press '''enter''' .</blockquote></li>
<li><blockquote>Now type '''‘a’''' and press Enter</blockquote></li>
<li><blockquote>We can see that the '''console''' shows ‘'''a’''' as undefined.</blockquote></li></ul>
|-
|
Show '''Xcos window''' and '''context menu'''

'''a=1'''
|
<ul>
<li><blockquote>Next, in the menu bar of the '''Untitled-Xcos window,''' click on '''Simulation'''.</blockquote></li>
<li><blockquote>In the drop down menu select the '''set context''' option.</blockquote></li>
<li><blockquote>'''set context''' popup window appears.</blockquote></li>
<li><blockquote>Type a=1 in the window and click ok.</blockquote></li></ul>
|-
| Show '''Xcos window'''
|
Now we execute the simulation again''':'''

<ul>
<li><blockquote>Go to the '''toolbar''' and click '''start.'''</blockquote></li>
<li><blockquote>Click '''ok''' in the warning window.</blockquote></li>
<li><blockquote>Then switch to the graphic window</blockquote></li>
<li><blockquote>We can see that the '''slope''' of '''output RAMP''' changed to '''‘a’'''.</blockquote></li></ul>
|-
|
Show Slide :

'''Advantages of Context menu'''
|
<ul>
<li><blockquote>Using the '''set context menu''' we can include the variables in the simulation itself.</blockquote></li>
<li><blockquote>We need not carry an additional '''sci file''' just to initialize the variable.</blockquote></li></ul>
|-

'''Summary'''
|
This brings us to the end of this tutorial. Let us summarise.

In this tutorial, we have learnt to:

<ul>
<li><blockquote>Pass variables from '''Scilab''' '''Console''' to '''Xcos.'''</blockquote></li>
<li><blockquote>Pass variables from '''context menu''' to '''Xcos.'''</blockquote></li></ul>

Show Slide:

Objects to calculate '''simple''' and '''compound interest'''
|
To calculate the '''interest''', we need three '''Edit boxes''' to take user inputs.

<ul>
<li><blockquote>The first '''Edit box''' for principal amount.</blockquote></li>
<li><blockquote>The second '''Edit box''' for rate of interest.</blockquote></li>
<li><blockquote>The third '''Edit box''' for time.</blockquote></li></ul>

After that, we need two '''Radiobuttons''' to calculate Simple and Compound interest.

Lastly, one '''Text''' box is required to display the answer.
|-
|
Cursor on '''GUIBuilder''' Palette,

Video-editor: Please put a textbox on screen. “guiFigure.sce”.

Hover over '''GUIBuilder''' Palette and '''Graphic window number 1.'''

Hover over three '''Edit''' boxes and one '''Text''' box
|
I have already opened the '''guiFigure.sce''' file using the '''GUIBuilder toolbox'''.

The '''GUIBuilder Palette''' and '''Graphic window number 1''' open up.

The graphic window shows the '''GUI''' with three '''Edit''' boxes and one '''Text''' box.
|-
|
Cursor on '''GUIBuilder Palette,'''

hover over the first '''Edit''' box.

Video-editor: Please put a textbox on screen. “String: Enter principal amount, Tag: ed_principal”
| The first '''Edit''' box has the '''String''' ‘'''Enter principal amount’''' with '''Tag ‘ed_principal’.'''
|-
|
Cursor on '''GUIBuilder''' Palette,

hover over the second '''Edit''' box.

Video-editor: Please put a textbox on screen. “String: Enter rate of interest, Tag: ed_rate”
| The second '''Edit''' box has the '''String ‘Enter rate of interest’''' with '''Tag ‘ed_rate’.'''
|-
|
Cursor on '''GUIBuilder''' Palette,

hover over the third '''Edit''' box. Video-editor: Please put a textbox on screen. “String: Enter time, Tag: ed_time”
| The third '''Edit''' box has the '''String ‘Enter time’''' with '''Tag ‘ed_time’.'''
|-
|
Cursor on '''GUIBuilder''' Palette,

hover over the '''Text''' box.

Video-editor: Please put a textbox on screen. “String: UnName4, Tag: txt_answer”
| The '''Text''' box has the '''String ‘UnName4’''' with '''Tag ‘txt_answer’'''.
|-
|

| Now l will add two '''Radiobuttons''' for '''Simple interest''' and '''Compound interest'''.
|-
|
On '''GUIBuilder Palette''',

click '''Radiobutton.'''
| Go to '''GUIBuilder Palette''' and click on '''Radiobutton'''.
|-
|
On '''Scilab Multiple Values Request''' window,

type '''rd_simple''' and type '''Simple interest.'''

Click on '''OK.'''
|
Let us type '''rd_simple''' as the '''Tag''' and '''Simple interest''' as the '''String'''.

Then click on '''OK'''.
|-
|
On '''Graphic window number 1,'''

place '''Radiobutton''' in the middle left.

Hover cursor over '''Simple''' '''interest''' '''Radiobutton'''.
|
Let us place this '''Radiobutton''' in the middle left of '''Graphic window number 1'''.

'''‘Simple interest’ Radio button''' appears.
|-
|
On '''GUIBuilder Palette''',

click '''Radiobutton.'''
| Let us take another '''Radiobutton''' for the '''Compound interest'''.
|-
|
On '''Scilab Multiple Values Request''' window,

type '''rd_compound''' and type '''Compound interest.'''

Click on '''OK.'''
|
Now I will type '''rd_compound''' as the '''Tag''' and ‘'''Compound interest’''' as the '''String'''.

Then click on '''OK'''.
|-
|
On '''Graphic window number 1,'''

place '''Radiobutton''' in the middle right.

Hover cursor over '''Radiobutton'''
|
Place this '''Radiobutton''' next to the '''Simple interest Radiobutton'''.

‘'''Compound interest’ Radiobutton''' appears.
|-
|

| Now the '''GUI''' part is completed.
|-
|
On '''GUIBuilder Palette''' window,

'''Generate>>Generate GUI code.'''
|
Let us save the file.

Go to the '''GUIBuilder Palette'''.

Click on '''Generate''' and then on the '''Generate GUI code'''.
|-
|
Save as '''interest-calculator'''.

Click on '''Save.'''

Video-editor: Pls put a textbox on screen. “In Ubuntu Linux OS, click on Ok button.”
|
I will save this file as '''interest-calculator.'''

Click on '''Save'''.
|-
|
On '''GUI created window,'''

click on '''OK.'''
|
A pop up opens with a message “'''GUI created successfully'''.”

Click on '''OK'''.
|-
|
On '''SciNotes''' window,

highlight '''handles''' for '''principal, rate, time, simple interest, compound interest''' and '''answer'''.
|
You can see that the corresponding '''Scilab code''' has been generated.

Notice the '''handles''' and '''properties''' of the objects we took on a '''graphic window'''.
|-
| Highlight '''handles.ed_principal'''.
| '''handles.ed_principal''' is the '''handle''' for principal amount.
|-
| Highlight '''handles.ed_rate'''.
| '''handles.ed_rate''' is the '''handle''' for rate.
|-
| Highlight '''handles.ed_time'''.
| '''handles.ed_time''' is the '''handle''' for time.
|-
| Highlight '''handles.txt_answer'''.
| '''handles.txt_answer''' is the '''handle''' for answer'''.'''
|-
| Highlight '''handles.rd_simple'''.
| '''handles.rd_simple''' is the '''handle''' for simple interest.
|-
| Highlight '''handles.rd_compound'''.
| '''handles.rd_compound''' is the '''handle''' for compound interest.
|-
|
Hover cursor over '''rd_simple_callback'''

function.
| Now let us write a '''function definition''' for '''rd_simple_callback function'''.
|-
|
Cursor on '''SciNotes''' window,

type within '''rd_simple_callback'''.

'''handles.rd_simple.value = 1'''

'''handles.rd_compound.value = 0'''

'''Principal = strtod(handles.ed_principal.string)'''

'''Rate = strtod(handles.ed_rate.string)'''

'''Time = strtod(handles.ed_time.string)'''

'''SI = (Principal * Rate * Time)/100'''

'''handles.txt_answer.string = string(SI)'''
|
Enter the code as seen here with the same '''syntax'''.

The same code can be found under the code files section.

You can use it as explained earlier in this tutorial.
|-
|
Highlight,

'''handles.rd_simple.value = 1'''

'''handles.rd_compound.value = 0'''
|
After clicking the '''Simple interest Radiobutton-'''

<ul>
<li><blockquote>This line will select the '''Simple interest Radiobutton'''.</blockquote></li>
<li><blockquote>The following line will deselect the '''Compound interest''' '''Radiobutton'''.</blockquote></li></ul>

This way only one '''button''' remains selected.
|-
|
Highlight,

'''Principal = strtod(handles.ed_principal.string)'''
| Next line then assigns the user input for principal value to variable '''‘Principal’'''.
|-
|
Highlight,

'''Rate = strtod(handles.ed_rate.string)'''
| Its next line assigns the user input for rate of interest to variable '''‘Rate’'''.
|-
|
Highlight,

'''Time = strtod(handles.ed_time.string)'''
| The further line assigns the user input for time to the variable '''‘Time’'''.
|-
|
Highlight,

'''SI = (Principal * Rate * Time)/100'''
|
Notice the next line.

This equation will perform the calculations.

The final result will be stored in the variable '''‘SI''''.
|-
|
Highlight,

'''handles.txt_answer.string = string(SI)'''
| The last line will give the value of the variable '''‘SI’''' to the '''Text''' box.
|-
| Hover cursor over '''rd_compound_callback''' function.
| Next I will write a function definition for '''rd_compound_callback''' function'''.'''
|-
|
Cursor on '''SciNotes''' window,

type within '''rd_compound_callback'''.

'''handles.rd_compound.value = 1'''

'''handles.rd_simple.value = 0'''

'''Principal = strtod(handles.ed_principal.string)'''

'''Rate = strtod(handles.ed_rate.string)'''

'''Time = strtod(handles.ed_time.string)'''

'''CI = (Principal *(1+( Rate/100))^ Time) - Principal'''

'''handles.txt_answer.string = string(CI)'''
|
Enter the code as seen here with the same '''syntax'''.

The same code can be found under the '''Code files''' section.
|-
|
Highlight,

'''handles.rd_compound.value = 1'''

'''handles.rd_simple.value = 0'''
|
This action is similar to what we have seen earlier.

After clicking the '''Compound interest''' '''Radiobutton-'''

<ul>
<li><blockquote>The first line will now select the '''Compound interest''' '''Radiobutton'''.</blockquote></li>
<li><blockquote>The next line will deselect the '''Simple interest Radiobutton'''.</blockquote></li></ul>
|-
|
Highlight,

'''Principal = strtod(handles.ed_principal.string)Rate = strtod(handles.ed_rate.string)'''

'''Time = strtod(handles.ed_time.string)'''
| Notice the next three lines are the same as in the '''rd_simple_callback function.'''
|-
|
Highlight,

'''CI = (Principal *(1+( Rate/100))^ Time) - Principal'''
|
The next line will calculate the '''Compound interest'''.

The final result will be stored in '''variable ‘CI'.'''
|-
|
Highlight,

'''handles.txt_answer.string = string(CI)'''
| The last line will give the value of '''variable ‘CI’''' to the '''Text''' box.
|-
| Press '''Ctrl+S.'''
| Let us save the '''Scilab code''' by pressing '''Ctrl''' and '''S''' keys together.
|-
|
On '''Scinotes''' window,

'''Execute'''>>'''file''' '''with echo'''
|
Execute this by clicking '''Execute''' on the '''menubar''' and then on '''File with echo'''.

'''Graphic window number 2''' opens.
|-
|
On '''Graphic window number 2,'''

delete '''Enter the principal amount here. '''

Type '''8000.'''

Delete '''Enter rate of interest.'''

Type '''7'''.

Delete '''Enter time.'''

Type '''3'''.
|
Now let us test the '''GUI.'''

Delete the '''string “Enter principal amount”''' from the '''Edit''' box and type '''8000'''.

Delete the '''string “Enter rate of interest”''' from the '''Edit''' box and type '''7'''.

Delete the '''string “Enter time”''' from the '''Edit''' box and type '''3'''.
|-
|
On '''Graphic window number 1,'''

click on '''Simple interest radiobutton'''.

Hover cursor over '''Text''' box.
|
Then click on the '''Simple''' '''interest''' '''Radiobutton.'''

The '''Text''' box shows the desired answer of '''1680''' as expected.
|-
|
On '''Graphic window number 1,'''

click on '''Compound interest radiobutton'''.

Show Slide:

'''What is Checkbox?'''
|
A '''Checkbox''' is a button with two states.

It is used when a user wants to make multiple independent choices.
|-
|

|
Let us begin with creating the '''GUI'''.

I have opened the '''GUIBuilder toolbox'''.
|-
|
Cursor on '''GUIBuilder Palette''',

click '''Checkbox.'''
| Go to '''GUIBuilder''' '''Palette''' and click on '''Checkbox'''.
|-
|
On '''Scilab Multiple Values Request''' window,

type '''chk_sine''' as '''Tag''',

type '''sin(t)''' as '''String.'''

Click on '''OK.'''
|
Type '''chk_sine''' as the '''Tag''' and '''sin(t)''' as the '''String'''.

Then click on '''OK'''.
|-
|
On '''Graphic window number 1,'''

place the '''Checkbox''' in the window's top left side.

Hover cursor over '''Checkbox'''.
|
Place the '''Checkbox''' in the window's top left side by considering a suitable size.

A '''sin(t) Checkbox''' appears.
|-
|
On '''GUIBuilder Palette''',

hover over '''cos(t) Checkbox.'''

Video-editor: Please put a textbox on screen. “Tag: chk_cosine, String: cos(t)”
|
In the similar way, I have taken another '''Checkbox''' for the '''cosine function'''.

I have written '''chk_cosine''' as the '''Tag''' and '''cos(t)''' as the '''String'''.

By considering the suitable size, I have placed it below the '''sin(t) Checkbox'''.

Pause the tutorial and do likewise in your '''GUI interface'''.
|-
| On '''GUIBuilder Palette''',
| To display the response of a system, we need '''Axes'''.
|-
|
On '''Graphic window number 1,'''

hover over '''Axes'''.

Video-editor: Please put a textbox on screen. “Tag: ax_response, String: System Response”
|
Hence I have taken an '''Axes''' with '''ax_response''' as '''Tag''' and '''System Response''' as '''String'''.

Notice that I have placed it on the right side of the window.

It appears like a '''box''' with a black border'''.'''

Again, pause the tutorial and do likewise in your '''GUI interface'''.
|-
|

| Now the '''GUI''' part is completed.
|-
|
On '''GUIBuilder Palette''' window,

'''Generate>>Generate GUI code.'''
|
Let us generate the '''Scilab code''' file for this.

Go to the '''GUIBuilder Palette'''.

Click on '''Generate''' and then on the '''Generate GUI code.'''
|-
|
Save as '''finding_wave'''.

Click on '''Save.'''

Video-editor: Pls put a textbox on screen. “In Ubuntu Linux OS, click on Ok button.”
|
I will save this file as '''finding_wave.'''

Click on '''Save'''.
|-
|
On '''GUI created window,'''

Click on '''OK.'''
|
A pop up opens with the message “'''GUI created successfully'''.”

Click on '''OK.'''
|-
|
On '''SciNotes''' window,

highlight '''handles''' for '''sine''', '''cosine''' and '''axes'''.
|
You can see that the corresponding '''Scilab code''' has been generated.

Notice the '''handles''' and '''properties''' of the objects we took on a '''graphic window'''.
|-
| Highlight '''handles.chk_sine'''.
| '''handles.chk_sine''' is the '''handle''' for '''sine Checkbox.'''
|-
| Highlight '''handles.chk_cosine'''.
| '''handles.chk_cosine''' is the '''handle''' for '''cosine Checkbox.'''
|-
| Highlight '''handles.ax_response'''.
| '''handles.ax_response''' is the '''handle''' for '''Axes.'''
|-
| Hover cursor over '''chk_sine_callback''' function.
| Now let us write a '''function definition''' within the '''chk_sine_callback function'''.
|-
|
Cursor on '''SciNotes''' window,

type within '''chk_sine_callback'''.

Type,

'''t = 0:0.1:2*%pi;'''

'''if handles.chk_sine.Value == 1'''

'''then plot(t,sin(t))'''

'''else'''

'''plot(t,sin(t),'w')'''

'''end'''
|
Enter the code as seen here with the same '''syntax'''.

The same code can be found under the '''Code files''' section.

You can use it as explained earlier in this tutorial.
|-
|
Highlight,

'''t = 0:0.1:2*%pi;'''
| The first line defines the range of '''t''' from '''0''' to '''2 pi''' with a step size of '''0.1'''.
|-
|
Highlight,

'''if handles.chk_sine.Value == 1'''

'''then plot(t,sin(t))'''

'''else'''

'''plot(t,sin(t),'w')'''

'''end'''
|
Further an '''if else''' statement is defined.

The '''checkbox''' for '''sin(t)''' is checked if the value is set to 1.

So, if it is checked then the response of the '''sine''' wave is plotted.

If it is unchecked, then an invisible response will be plotted with white color.
|-
|
Cursor on '''SciNotes''' window,

type within '''chk_cosine_callback'''.

Type,

'''t = 0:0.1:2*%pi;'''

'''if handles.chk_cosine.Value == 1'''

'''then plot(t,cos(t))'''

'''else'''

'''plot(t,cos(t),'w')'''

'''end'''
|
Next I will write a function definition for '''chk_cosine_callback function.'''

Enter the code as seen here with the same '''syntax''' as explained earlier.

The same code can also be found under the '''Code files''' section.
|-
|
Highlight,

'''t = 0:0.1:2*%pi;'''
|
The first line is the same as seen in the '''chk_sine_callback function.'''

It will define the range of '''‘t’'''.
|-
|
Highlight,

'''if handles.chk_cosine.Value == 1'''

'''then plot(t,cos(t))'''

'''else'''

'''plot(t,cos(t),'w')'''

'''end'''
|
Further an '''if else''' statement for '''cos(t) checkbox''' is defined.

This action is similar to what we have seen previously.

If the '''checkbox''' for '''cos(t)''' is checked, then it will plot the response of the '''cosine''' wave.

If it is unchecked, then an invisible response will be plotted with white color.
|-
| Press '''Ctrl+S.'''
| Now let us save the '''Scilab code''' by pressing '''Ctrl''' and '''S''' keys together.
|-
|
On '''Scinotes''' window,

'''Execute'''>>'''file''' '''with echo.'''
| To execute, click on '''Execute''' on the '''menu bar''' and then on '''file with echo'''.
|-
|
On '''Graphic window number 2,'''

check the '''sin(t) checkbox.'''

Hover cursor over the '''Axes'''.
|
Now check the '''sin(t) checkbox.'''

You will see the time response of the '''sine function''' on the '''Axes'''.
|-
|
On '''Graphic window number 2,'''

check the '''cos(t) checkbox.'''

Hover cursor over the '''Axes'''.
|
Let us now check the '''cos(t)''' '''checkbox'''.

'''Axes''' shows the time response of the '''cosine function''' along with the '''sine''' '''function'''.
|-
|
On '''Graphic window number 2,'''

uncheck the '''sin(t) checkbox'''

check the '''sin(t) checkbox.'''
|
Now uncheck the '''sin(t)''' '''checkbox.'''

The response of '''sine''' function is not visible now.

If we check the '''sin(t)''' '''checkbox''' then the '''sine function''' response is again visible.

This way we can perform the basic plotting using '''GUI.'''

|
On '''GUIBuilder toolbox''',

hover cursor over '''GUIBuilder Palette''' window and '''Graphic window number 1'''.
|
I have already opened the '''GUIBuilder toolbox.'''

As we can see there are two windows.

The '''GUIBuilder Palette''' window is located on the left side.

The '''Graphic window number 1''' is on the right side.

Let us start by creating the '''GUI'''.
|-
|

|
To calculate the '''exponent''' of a number, we need two inputs.

The first input is a '''base''' number and the second input is an '''exponent'''.
|-
|
On '''GUIBuilder Palette''',

click '''Edit.'''
| For the first input, go to the '''GUIBuilder Palette''' and click on '''Edit'''.
|-
|
On '''Scilab Multiple Values Request''' window,

type '''ed_base''' in '''Tag''' field,

type '''Enter''' '''the base''' in '''String''' field'''.'''

Click on '''OK.'''
|
A window named '''Scilab Multiple Values Request''' will open.

Type '''ed underscore base''' as the '''Tag''' and '''Enter the base''' as the '''String'''.

Then click on '''OK'''.
|-
|
On '''Graphic window number 1,'''

Place the '''Edit''' box in window's top left side.

Hover cursor over an '''Edit''' box.
|
Switch to the '''Graphic window number 1'''.

Place the '''Edit box''' in the window's top left side, by considering a suitable size.

An '''Edit box''' with the '''string “Enter the base”''' appears.
|-
|
On '''GUIBuilder palette''',

click on '''Edit'''.
| Let us take another '''Edit box''' for the second input.
|-
|
On '''Scilab Multiple Values Request''' window''','''

type '''ed_exponent''' in '''Tag''' field,

type '''Enter''' '''an exponent''' in '''String''' field'''.'''

Click on '''OK.'''
|
I will type '''ed underscore exponent''' as the '''Tag''' and '''Enter''' '''an exponent''' as the '''String'''.

Then click on '''OK'''.
|-
|
On '''Graphic window number 1,'''

Place the '''Edit''' box in window's top right side.

Hover cursor over an '''Edit''' box.
|
Consider a suitable size of the '''Edit''' box.

Place it in the top right side of the '''Graphic window number 1'''.

An '''Edit box''' with the '''string “Enter an exponent”''' appears.
|-
|
On '''GUIBuilder Palette''' window,

click on '''Text'''.
| To display '''output''', go to the '''GUIBuilder Palette''' and click on '''Text'''.
|-
|
On '''Scilab Multiple Values Request''' window,

type '''txt_output''' in '''Tag''' field'''.'''

Click on '''OK.'''
|
I will type '''txt underscore output''' as the '''Tag'''.

Keep the '''String''' field empty.

We will not display any messages until we receive from the '''user'''.

Then click on '''OK'''.
|-
|
On '''Graphic window number 1,'''

place the '''Text''' box at bottom.

Hover cursor over '''Text''' box.
|
I will place the '''Text box''' at the bottom of the '''Graphic window number 1'''.

A '''Text box''' with the '''string “UnName3”''' appears.
|-
|
On '''GUIBuilder Palette window''',

click on '''Pushbutton'''.
|
To perform the calculations, I will add a '''pushbutton'''.

Go to '''GUIBuilder Palette''' and click on '''Pushbutton'''.
|-
|
On the '''Scilab Multiple Values Request''' window,

type '''pb_cal''' in '''Tag''' field and type '''Calculate''' in '''String''' field'''.'''

Click on '''OK.'''
|
Further I will type '''pb underscore cal''' as the '''Tag''' and '''Calculate''' as the '''String''' for the '''pushbutton'''.

Then click on '''OK'''.
|-
|
On '''Graphic window number 1,'''

place the '''Pushbutton''' in the middle.

Hover cursor over '''Pushbutton.'''

Hover cursor over two '''Edit''' boxes and '''Text''' box.
|
Let us place the '''Pushbutton''' in the middle of the '''Graphic window number 1'''.

A '''pushbutton''' with the '''string “Calculate”''' appears.

As a result, the '''pushbutton''' has two '''Edit boxes''' above it and a '''Text box''' below it.
|-
|

| Now the '''GUI''' part is completed.
|-
|
On '''GUIBuilder Palette''' window,

'''Generate>>Generate GUI code.'''
|
To save this file, go to the '''GUIBuilder Palette'''.

Click on '''Generate''' and then on the '''Generate GUI code'''.
|-
|
On '''uiputfile''' window,

save as '''exponent-calculator'''.

Click on '''Save.'''

Video-editor: Pls put a textbox on screen. “In Ubuntu Linux OS, click on Ok button.”
|
I will save this file as '''exponent-calculator.'''

Click on '''Save'''.
|-
|
On '''GUI created window,'''

click on '''OK.'''
|
A pop-up opens with the message “'''GUI created successfully'''.”

Click on '''OK'''.
|-
|
On '''SciNotes''' window,

highlight '''handles''' for '''base, exponent output''' and '''Calculate'''.
|
We can see that the corresponding '''Scilab code''' has been generated.

Notice the '''handles''' and '''properties''' of the objects we took on a '''graphic window'''.
|-
| Highlight '''handles.ed_base'''.
| '''handles dot ed underscore base''' is the '''handle''' for '''base'''.
|-
| Highlight '''handles.ed_exponent'''.
| '''handles dot ed underscore exponent''' is the '''handle''' for '''exponent'''.
|-
| Highlight '''handles.txt_output.'''.
| '''handles dot txt underscore output''' is the '''handle''' for '''output.'''
|-
| Highlight '''handles.pb_cal.'''
| '''handles dot pb underscore cal''' is the '''handle''' for '''Pushbutton.'''
|-
| Hover cursor over '''pb_cal_callback''' function.
| Now let us write a '''function definition''' for '''pb_cal_callback function'''.
|-
|
Cursor on '''SciNotes''' window,

type within '''pb_cal_callback'''.

Type,

'''base = strtod(handles.ed_base.string)'''

'''exponent = strtod(handles.ed_exponent.string)'''

'''out = base^exponent'''

'''handles.txt_output.string = string(out)'''
|
Enter the code as seen here with the same syntax.

The same code can be found under the '''Code files''' section.

You can use it as explained earlier in this tutorial.
|-
|
Highlight,

'''base = strtod(handles.ed_base.string)'''
| The first line assigns the user input for a '''base''' value to the '''variable ‘base’'''.
|-
|
Highlight,

'''exponent = strtod(handles.ed_exponent.string)'''
| The second line assigns the user input for an '''exponent''' to the '''variable ‘exponent’'''.
|-
|
On '''SciNotes''' window,

within '''pb_cal_callback.'''

highlight '''strtod''' command.
|
It is not possible to do calculations when the value is in '''string''' format.

Hence I have put the '''handles''' inside the '''strtod command.'''

This '''command''' will convert the value from the '''string''' format to a '''decimal''' format.
|-
|
Highlight,

'''out = base^exponent'''
|
Notice the next line.

This equation will perform the calculations.

The final result will be stored in the '''variable ‘out.''''
|-
|
Highlight,

'''handles.txt_output.string = string(out)'''
| The last line will give the value of a '''variable ‘out’''' to the '''Text box'''.
|-
| Press '''Ctrl+S.'''
| Let us save all our work by pressing '''Control''' and '''S''' keys together.
|-
|
On '''Scinotes''' window,

'''Execute'''>>'''file''' '''with echo'''
|
'''Execute''' this by clicking '''Execute''' on the '''menubar''' and then on '''File with echo'''.

The '''Graphic window number 2''' opens.
|-
|
On '''Graphic window number 2,'''

delete '''Enter the base. '''

Type '''2.'''

Delete '''Enter an exponent.'''

Type '''4'''.
|
Now let us test the '''GUI.'''

I will calculate '''4''' to the '''power 2'''.

Delete the '''string “Enter the base”''' from the '''Edit box''' and type '''4'''.

Delete the '''string “Enter an exponent”''' from the '''Edit box''' and type '''2'''.
|-
|
On '''Graphic window number 2,'''

click on '''Calculate Pushbutton'''.

Hover cursor over '''Text''' box.
|
Then click on the '''Calculate Pushbutton.'''

The '''Text box''' shows the desired answer of '''16''' as we expected.

This way we can perform numeric calculations using '''GUI''' in '''Scilab'''.

'''“Max value” 10''' represents the maximum value in the range of the slider scale.

And '''“Normalization” 1''' represents the interval value of the slider scale.

Click on '''OK'''.
|-
|
Point to the '''black input '''of '''CSCOPE.'''

Point to the''' red input '''of '''CSCOPE.'''
|
The black '''input port '''in the '''CSCOPE''' carries the data values.

The red '''input port '''in the '''CSCOPE''' represents the events.

The '''red input '''can connect only to a block that generates the events.
|-
|
Cursor on the '''Palette browser window''',

'''Sources>>CLOCK _c.'''

As per narration.
|
To generate the events, go to the '''Palette browser-Xcos window'''.

Click on the '''Sources '''Palette.

Then click on the '''CLOCK underscore c''' block.

Drag and drop the '''CLOCK underscore c''' block above the '''CSCOPE '''block.
|-
| Hover cursor on '''Untitled-Xcos window'''.
|
We have collected all the required blocks in the '''Untitled-Xcos window '''to do the simulation.

Let us now connect the blocks together.
|-
|
On '''Untitled-Xcos window''',

Connect as per narration'''.'''
|
Select the '''black output port''' of the '''TKSCALE''' block.

Connect it to the '''black input port''' of the '''CSCOPE '''block.
|-
|
On '''Untitled-Xcos window''',

Connect as per narration'''.'''
|
Next select the red '''output port''' of the '''CLOCK underscore c''' block.

Connect it to the red '''input port''' of the '''CSCOPE''' block.
|-
|
On '''Untitled-Xcos window,'''

Connect as per narration
|
Next select the '''red input port '''of the '''TKSCALE '''block.

Connect it to the '''line '''connecting '''CLOCK underscore c''' and '''CSCOPE''' block.
|-
|
On '''Untitled-Xcos window,'''

Connect as per narration
|
Use the left mouse click to create line bends and then connect it to the line.

Now let us simulate this file with the default values.
|-
|
On '''Untitled-Xcos window,'''

Click on '''start'''.
|
To start the '''simulation''', go to the toolbar of the '''Untitled-Xcos window'''.

Then click on the '''Start '''button that is of the shape of the play button.
|-
| Cursor on the '''Slider '''and the '''Graphic window'''.
|
Two windows get opened.

The left window will display the '''slider'''.

The right '''Graphic window '''will display the output of the system.
|-
|
Hover cursor over '''slider'''
|
Notice that the '''slider '''opens and closes quickly.

It doesn’t give a chance to make use of this '''slider'''.

This is happening because '''Xcos '''is trying to simulate this file at computer time.
|-
|
Close '''Graphic window'''
| To handle this problem, first close the '''Graphic window'''.
|-
|
On '''Untitled-Xcos window''',

'''Simulation>>Setup'''
|
Then go to the menu bar of the '''Untitled-Xcos window '''and click on '''Simulation'''.

Then click on '''Setup'''.
|-
|
On '''Set parameters window''',

Cursor on '''Real time scaling'''
|
A pop up window named '''Set parameters '''appears.

We will change the default value of the '''real time scaling '''to '''1.'''
|-
|
Hover cursor over '''Set parameters '''window.

Click on '''OK'''.
|
Keep the other parameters unchanged.

Then click on '''OK.'''
|-
|
On '''Untitled-Xcos window''',

Click on '''Start'''.
|
To start the '''simulation,''' go to the toolbar of the '''Untitled-Xcos window'''.

Click on the '''Start '''button.
|-
| Cursor on '''Graphic window '''and '''slider'''
| A '''graphic window''' and the '''slider''' will open.
|-
|
Hover cursor over the '''slider'''.

Hover cursor over '''slider '''and '''Graphic window.'''
|
Now I’ll change the value of a parameter using a '''slider'''.

Notice that I am changing the value while the simulation is running.

Observe the changes on a '''Graphic window '''as I change the '''slider '''value.

So this is how we can make the '''Xcos '''simulation interactive using a '''slider'''.
