|-
| 00:01
|Welcome to the spoken tutorial on '''File handling''' using '''Scilab'''.

|-
| 00:06
| In this tutorial, we will learn:

|-
|00:08
|* '''Input Function '''

|-
|00:10
|* '''Formatting the Output'''

|-
| 00:12
|* '''save function '''

|-
|00:14
|* '''load function '''.

|-
| 00:16
|For demonstration I am using '''Ubuntu Linux 12.04''' operating system with '''Scilab version 5.3.3''' installed.

|-
| 00:26
| You should have basic knowledge of '''Scilab.'''

|-
|00:29
| If not, for relevant spoken tutorials on Scilab please visit '''spoken hyphen tutorial dot org'''.

|-
|00:37
|The '''input()''' function is used to take the input from the user.

|-
|00:42
| It provides a prompt in the text string for user input.

|-

| 00:47

| It waits for input from the keyboard.

|-
| 00:51
| If nothing but a carriage return is entered at the prompt, '''input()''' function returns an empty matrix.

|-
| 00:59
| The '''input''' function can be written in two ways:

|-
|01:03
| First, x= input into brackets "message to display"

|-
|01:09
|second, x= input into brackets ("message to display", "strings").

|-
|01:17
| In the second example, the second argument is “string”.

|-
|01:22
|So the output is a character string which is the expression entered using the keyboard.

|-

|01:29

|Switch to the '''Scilab console''' window and type,

|-

|01:33

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

|-

| 01:49

|Type 25 and press Enter.

|-

| 01:53
|| 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.

|-

| 02:14
|| type 25 and press Enter.

|-

|02:18

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

|-

|02:25

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

|-

|02:30

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

|-

|02:34

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

|-

|02:42

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

|-

|02:45

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

|-
|02:51
|Similarly, '''typeof(y)''' and press Enter.

|-
| 02:57
||You can see it yourself that the first answer stored in x is of type '''constant''' and

|-
| 03:04
||second answer stored in y, with the argument '''“string”''' included in the command, is of '''type string.'''

|-

|03:12

|| Let us now see how to format the output that is displayed on the console.

|-

|03:17

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

|-

|03:22

| '''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.

|-
|03:38
| 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.

|-
|04:12
| 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

|-
|05:28
| '''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

|-

| 05:47
|| continue at a later stage, type '''save thissession'''.

|-

|05:52

||This will save the current values of all variables to a file called '''thissession.'''

|-

|05:58

||This file cannot be edited.

|-

| 06:01

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

|-

| 06:04

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

|-
|06:08
| and the computation can be resumed where you left off.

|-

| 06:13

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

|-

|06:16

||The '''save()''' command saves all the '''Scilab''' current variables in a binary file.

|-

|06:22

| 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.

|-

| 07:22

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

|-

| 07:28

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

|-

|07:34

|'''save''' space '''matrix''' dash '''a''' dash '''b'''

|-

|07:42

| 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.

|-

|08:03

|| 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.

|-

| 08:12

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

| 08:17

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

|-

| 08:22

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

|-

| 08:26

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

|-

| 08:29

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

|-

| 08:34

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

|-

| 08:39

| ->'''a '''

|-

| 08:40

|'''b'''

|-

| 08:41

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

|-

| 08:49

|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.

|-

| 09:08

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

|-

| 09:14

| Type -->a and-->b

|-

| 09:18

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

|-

| 09:23
