Blank spaces around the “=”, “+”, and “-“operators are optional, but they

improve readability.

Command Line Editing

Various arrow and control keys on your keyboard allow you to recall, edit,

and reuse statements you have typed earlier. For example, suppose you

mistakenly enter:

“rho = (1 + sqt(5))/2”

You have misspelled square root:

t. Matlab responds with:

“Undefined function or variable 'sqt'”

Instead of retyping the entire line, simply press the key. The statement

you typed is redisplayed. Use the key to move the cursor over and insert

the missing “r”. Repeated use of the key recalls earlier lines. Typing a few

characters and then the key finds a previous line that begins with those

characters. You can also copy previously executed statements from the

command history window [2].

Interrupting a Command, a Script or a Function

It is often that a user writes a command (or script or a function) that enters

to an endless loop, so it keeps running. Pressing [Ctrl]+[C] once or few times,

it will terminate the execution. Sometimes where the user runs a script that

calls other functions, the interruption with [Ctrl]+[C] might take few seconds

to few minutes to take place.

Current Directory

On the command window toolbar, the user can find the current directory

address bar. Matlab file operations use the current directory and the search

path as reference points. Any file you want to run must either be in the

1 2 ... 16 17 18 19 20 21 22 23 24 25 26 ... 118 119
