IIT Bombay

The procedure to practise

1. You are given a set of spoken tutorials and fileseither in a CD or already copied on your Desk-top.

2. You will typically do one tutorial at a time.

3. The tutorials are numbered from 0 to 9.

4. Follow the tutorials in sequence for a betterunderstanding.

Please find out from the workshop co-ordinatorwhether Scilab is already installled.If so please skip the Section 1.

3. Right click on 02-Getting-Started.wmv

,click on Open with option and select VLC

Media Player to play the tutorial.

4. Follow the tutorial and reproduce all the com-mands on your Scilab Console as shown in thevideo.

5. Pause the tutorial when mentioned in thevideo and attempt any one assignment prob-lem given in the video and/or on the assign-ment sheet given to you.

6. At 5:34 - The diary() command stores theScilab session in a file after you issue the com-mand and not before that.

7. At 5:34 - Change the directory to Destinationwhere you have write access, preferably changeit to Desktop before issuing the diary() com-mand.

4. At 2:10 - Pause the tutorial, open Scilab editor,type the commands in the editor yourself andsave the file as helloworld.sce

5. At 3:25 - Type pwd to check the presentworking directory; change the directoryusing Change Directory shortcut icon tothe directory where you have saved thehelloworld.sce file before using the exec

command.

6 Conditional Branching:
