For Demonstration: Ubuntu Linux12.04 operating system is used with Scilab version 5.3.3 installed

|-
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:none;padding:0.097cm;"| Slide
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:1pt solid #000000;padding:0.097cm;"| Input Function:

The '''input() '''function

* is used to take the input from the user.
* provides a prompt in the text string for user input.
* waits for input from the keyboard.

If nothing but a carriage return is entered at the prompt, '''input()''' function returns an empty matrix.

|-
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:none;padding:0.097cm;"| Slide
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:1pt solid #000000;padding:0.097cm;"| The '''input''' function can be written in two ways as you see.

In the second example, the second argument is “'''string'''”.

So the output is a character string, which is the expression entered using the keyboard.

|-
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:none;padding:0.097cm;"| Scilab Console

--> x = input (“ Enter your age”)

--> y = input (“ Enter your age”, “string”)
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:1pt solid #000000;padding:0.097cm;"| Type the following on the''' Scilab Console'''

'''-->x is equal to input open bracket inside double quotes Enter your age colon close the bracket'''

I will enter a number say 25 here.

Its shows the output as

'''x <nowiki>=</nowiki>'''

'''25.'''

Now type

'''-->y is equal to input open bracket inside double quotes Enter your age comma inside double quotes string close the bracket.'''

I will enter a number say 25 here.

Its shows the output

'''y <nowiki>=</nowiki>'''

'''25 '''

|-
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:none;padding:0.097cm;"|
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:1pt solid #000000;padding:0.097cm;"| We see that in both the cases the input we entered, was a number 25.

|-
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:none;padding:0.097cm;"|
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:1pt solid #000000;padding:0.097cm;"| Now, let us check the type of variable that '''x''' and '''y''' are.

We are doing this to validate the use and importance of the argument “string”, given in the second example.

|-
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:none;padding:0.097cm;"| -->typeof(x)

-->typeof(y)
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:1pt solid #000000;padding:0.097cm;"| To check the type of variable, let us type

'''-->typeof(x)'''

'''ans is equal to '''

'''constant '''

'''-->typeof(y)'''

'''ans <nowiki>=</nowiki>'''

'''string '''

|-
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:none;padding:0.097cm;"|
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:1pt solid #000000;padding:0.097cm;"| You can see it yourself, that

* the first answer stored in x is of type '''constant''' and
* second answer stored in y, with the argument “'''string'''” included in the command, is of type '''string'''.

|-
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:none;padding:0.097cm;"| Slide
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:1pt solid #000000;padding:0.097cm;"| Let us now see how to format the output that is displayed on the console.

This can be done using the '''mprintf()''' function.

'''mprintf()''' function converts, formats and writes data on to the '''Scilab console'''.

It is an interface for C-coded version of '''printf''' function.

|-
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:none;padding:0.097cm;"|
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:1pt solid #000000;padding:0.097cm;"| Let us see an example for this.

Type the following on the '''Scilab Console'''

|-
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:none;padding:0.097cm;"| Scilab console

-->mprintf("Value of x=%d is taken as a CONSTANT, while value of y=%s is taken as a STRING", x , y)

'''Value of x=25 is taken as a CONSTANT,while value of y=25 '''

'''is taken as a STRING'''
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:1pt solid #000000;padding:0.097cm;"| '''-->mprintf open bracket open double quotes Value of x is equal to percentage d is taken as a CONSTANT comma while value of y is equal to percentage s is taken as a STRING close double quotes comma x comma y close the bracket'''

In the above example

* '''percentage d''' is used to insert an '''constant''' data stored in variable '''x''' and
* '''percentage s '''is used to insert a '''string''' data stored in variable '''y.'''

|-
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:none;padding:0.097cm;"| Slide
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:1pt solid #000000;padding:0.097cm;"| Now, let us discuss the use of '''save''' and '''load''' command.

To quit '''Scilab''' midway through a calcula-

tion and

continue at a later stage type

'''--> save thissession'''

This will save the current values of all variables to a file

called '''thissession'''.

This file cannot be edited.

It is in '''binary''' format.

When you next start '''Scilab''', type

'''--> load thissession'''

and the computation can be resumed where you left off.

The purpose of '''save''' and '''load''' function are

* The '''save() '''command saves the '''scilab''' current variables in a binary file.
* If the variable is a graphic handle, the '''save''' function saves all the corresponding graphics_entities definition.
* The file can be given either by its paths or by its descriptor previously given.

|-

* <tt>'''save(fd)'''</tt> saves all current variables in the file defined by the descriptor <tt>fd</tt>.
* <tt>'''save(filename,x,y)'''</tt> or <tt>'''save(fd,x,y)'''</tt> saves only named variables <tt>x</tt> and <tt>y</tt>.

--> save('matrix-a-b.dat', a, b)
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:1pt solid #000000;padding:0.097cm;"| Let us see an example to illustrate the '''save''' and '''load''' commands usage.

Let us define two matrices say '''a''' and '''b'''

-'''->a = eye(2,2)'''

'''-->b=ones(a)'''

'''--> save matrix-a-b '''

or it can also be written as

-'''->save('matrix-a-b.dat',a,b)'''

This saves the values of variables in a binary file '''matrix-a-b.dat''' in the present working directory.

You can browse the present working directory to check the existence of this binary file.

|-
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:none;padding:0.097cm;"| Scilab Console

| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:1pt solid #000000;padding:0.097cm;"| Now let us load the file back in to the variables.

Before this, let us clear the variables '''a '''and '''b'''

'''-->clear a space b'''

Let us cross check if these variables are really cleared.

-'''->a'''

'''!--error 4 '''

'''Undefined variable: a'''

'''-->b'''

'''!--error 4 '''

'''Undefined variable: b'''

|-
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:none;padding:0.097cm;"| Scilab Console

--> load('matrix-a-b.dat', 'a', 'b')

| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:1pt solid #000000;padding:0.097cm;"| Now let us load back the values from the binary files in these variables '''a''' and '''b''' using the '''load''' command.

'''Load open bracket open single quote matrix dash a dash b dot dat close quotes comma inside quotes a comma inside quotes b close the bracket'''

|-
| style="border-top:none;border-bottom:1pt solid #000000;border-left:1pt solid #000000;border-right:none;padding:0.097cm;"| --> a

'''-->a'''

'''-->b'''

You can see the values are loaded back in the variables.
