3. Variables in the workspace: All variables created by a script file are left in the global workspace. You can get information about them and access them, too: • Type who to see the variables present in your workspace. You should see the variables r, theta, x and y in the list. • Type whos to get more information about the variables and the workspace. • Type (theta' x' y'] to see the values of 8, # and y listed as three columns. All three variables are row vectors. Typing a single right quote (' on the keyboard) after their names transposes them and makes them column vectors. 4. Contents of the file: You can see the contents of an M-file without opening the file with an editor. The contents are displayed by the type command. To see the contents of circle... type type circle... 5. Hi line: The first commented line before any executable statement in a script file is called the HI line. It is this line that is searched by the lookfor command. Since the lookfor command is used to look for M-files with keywords in their description, you should put keywords in Hi line of all M- files you create. Type lookfor unit to see what MATLAB comes up with. Does it list the script file you just created!
