| 00:01 | Scilab વાપરીને File handling પરના આ સ્પોકન ટ્યુટોરિયલમાં તમારું સ્વાગત છે . |
| 00:06 | આ ટ્યુટોરીયલમાં આપણે શીખીશું : |
| 00:08 | * ઈનપુટ ફન્કશન |
| 00:10 | * આઉટપુટ ફોરમેટ કરવું |
| 00:12 | * ફન્કશનને સેવ કરવું |
| 00:14 | * ફન્કશન ને લોડ કરવું |
| 00:16 | પ્રદશન માટે હું ઉપયોગ કરી રહી છું સંસ્થાપિત Scilab version 5.3.3 ના સાથે Ubuntu Linux 12.04 ઓપરેટીંગ સીસ્ટમ. |
| 00:26 | તમને Scilab નું સામાન્ય જ્ઞાન હોવું જોઈએ. |
| 00:29 | જો નથી તો સંબંધિત ટ્યુટોરિયલ્સ માટે અમારી વેબસાઇટ જુઓ spoken hyphen tutorial dot org. |
| 00:37 | The input() યુઝરથી ઈનપુટ લેવા માટે ઉપયોગી છે. |
| 00:42 | આ યુઝર ઈનપુટ ના માટે ટેસ્ટ સ્ટ્રીંગમાં પ્રોમ્પ્ટ પૂરું પાડે છે. |
| 00:47 | આ કીબોર્ડ પાસેથી ઈનપુટની રાહ જુએ છે. |
| 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 : |
| 01:03 | પ્રથમ , x= input કૌંસમાં "message to display" |
| 01:09 | બીજું છે, x= input કૌંસમાં ("message to display", "strings"). |
| 01:17 | બીજા ઉદાહરણમાં બીજું આર્ગ્યુમેન્ટ “string” છે. |
| 01:22 | તો આઉટપુટ એક કેરેક્ટર સ્ટ્રીંગ છે જે કીબોર્ડનો ઉપયોગ કરીને ઉમેરાયેલું એક્ક્ષપ્રેશન છે. |
| 01:29 | Scilab console વિન્ડો પર જાવ અને ટાઇપ કરો, |
| 01:33 | x is equal to input ખુલ્લો કૌંસ ડબલ કોટમાં Enter your age ડબલ કોટ બંદ કરો કૌંસ બંદ કરો અને એન્ટર દબાવો. |
| 01:49 | 25 and press Enter. ટાઈપ કરો 25 અને એન્ટર દબાવો. |
| 01:53 | હવે ટાઈપ કરો -->y is equal to input કૌંસમાં ડબલ કોટમાં Enter your age ડબલ કોટ બંદ કરો comma ફરીથી ડબલ કોટમાં લખો string કૌંસ બંદ કરો અને એન્ટર દબાવો. |
| 02:14 | ટાઈપ કરો 25 અને એન્ટર દબાવો . |
| 02:18 | આપણે જોઈએ છીએ ક એ બંને પરિસ્થિતિઓમાં જે ઈનપુટ આપણે કીબોર્ડ થી ઉમેર્યું તે 25 છે. |
| 02:25 | ચાલો હવે x અને y ના પ્રકાર જોઈએ. |
| 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 | In this tutorial we learnt - |
| 09:24 | * Input function using input command |
| 09:28 | * Formatting the output using mprintf command |
| 09:31 | * save function |
| 09:33 | * load function |
