|* '''ફન્કશન ને લોડ કરવું'''

| પ્રદશન માટે હું ઉપયોગ કરી રહી છું સંસ્થાપિત '''Scilab version 5.3.3''' ના સાથે  '''Ubuntu Linux 12.04''' ઓપરેટીંગ સીસ્ટમ.

| 00:26

|The '''input()''' યુઝરથી ઈનપુટ લેવા માટે ઉપયોગી છે.  

|   આ યુઝર ઈનપુટ ના માટે  ટેસ્ટ સ્ટ્રીંગમાં પ્રોમ્પ્ટ પૂરું પાડે છે.  

 

| 00:47

 

| 00:51

|કઈ નહિ કરીએ અને '''carriage return''' એન્ટર કરીએ તો  '''input()''' ફન્કશન આપણને '''empty matrix'''  પાછુ આપે છે.   

| 00:59

| The '''input''' ફન્કશનને બે પ્રકારે લખી શકીએ છીએ :  

 

|'''x is equal to input''' open bracket inside double quotes '''Enter your age''' close the double quotes close the bracket and press '''Enter'''.  

 

|Type 25 and press Enter.  

 

|| Now type -->'''y is equal to input ''' into bracket into double quotes '''Enter your age''' close the double quotes comma again inside double quotes write '''string''' close the bracket and press Enter.  

|| type 25 and press Enter.  

 

|| We see that in both the cases the input we entered through keyboard, was a number 25.  

 

| Now, let us check the type of variable that x and y are.  

 

| Let us clear the console using '''clc''' command.  

 

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

 

|| To check the type of variable, let us type

 

| -->'''typeof''' into brackets '''x''' and press Enter.  

|Similarly, '''typeof(y)''' and press Enter.  

||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.'''  

 

|| 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.'''

 

| 03:28

 

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

| 03:34

| Let us see an example for this. Switch to the console.  

| Type-->'''mprintf''' into bracket into quotes type '''At iteration percent i comma Result is colon slash n alpha is equal to percentf comma 33 comma 0.535''' close the bracket.  

| Here 33 will be displayed in place of '''percent i''' (%i) and point 535 (0.535) will be displayed in place of '''percent f''' (%f) as a flow. Press Enter.

| 04:26

| This will give the output as  '''At iteration 33, Result is alpha is equal to 0.535000.'''  

| 04:39

|Clear the console. Now let us see another example.

| 04:44

|  '''mprintf open bracket''' into quotes '''Value of x is equal to percentage d is taken as a CONSTANT comma while value of y is equal to percent s is taken as a STRING '''close the quotes '''comma x comma y''' close the bracket.  

| 05:19

|In the above example percentage d (%d) is used to insert a constant data stored in variable x and

| '''percentage s''' (%s) is used to insert a '''string''' data stored in variable y. press Enter, you see the output.  

| 05:38

| Now, let us discuss the use of '''save''' and '''load''' commands.  

 

| 05:43

 

|To quit '''Scilab''' midway through a calculation and to

|| 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.  

 

| 06:01

 

|It is in '''binary''' format.  

 

| 06:04

 

| When you next start Scilab, type '''load thissession'''

| and the computation can be resumed where you left off.  

 

| 06:13

 

| The purpose of '''save''' and '''load''' functions are

 

||The '''save()''' command saves all 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.  

 

| 06:31

 

| The file can be given either by its path or by its descriptor previously given.  

 

| 06:37

 

|'''save(filename)''' saves all the current variables in a file defined by filename.  

 

| 06:45

 

| '''save into bracket fd''' saves all the current variables in the file defined by the descriptor '''fd'''.  

 

| 06:53

 

| '''save(filename,x,y)''' or '''save(fd,x,y)''' saves only named variables '''x''' and '''y'''.  

 

| 07:02

 

||Let us see an example to illustrate the '''save''' and '''load''' commands usage.  

 

| 07:07

 

||Switch back to the console. Let us define two matrices, say a and b.  

 

| 07:14

 

||-->'''a = eye''' of '''(2,2)''' and press Enter.  

 

|Type '''b=ones(a)''' and press Enter.  

 

|Clear the console using '''clc''' command. Now type

 

| or it can also be written as:  

 

| 07:46

 

| '''save into brackets into quotes matrix dash a dash b dot dat''' close the quotes '''comma a comma b''' close the bracket and press Enter.  

 

|| This saves the values of variables in a binary file 'matrix dash a dash b dot dat' (matrix-a-b.dat) in the present working directory.  

 

|You can see it here. I will close the file browser.  

 

| Now let us load the file back in to the variables.  

 

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

 

| Type '''clear a''' space '''b''', press Enter.  

 

| Let us cross check if these variables are really cleared.  

 

| ->'''a  '''  

 

| Now let us load back the values from the binary files in these variables a and b using the '''load command'''.  

 

|Type: '''load into bracket into quote matrix dash a dash b dot dat''' close the quotes '''comma into quotes a comma into quotes b''' close the bracket and press Enter.  

 

| Let us check the values in variables a and b. Clear the console.  

 

| Type -->a and-->b  

 

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