Entering Long Statements

If a statement does not fit on one line, use an ellipsis (three periods), ...,

followed by Return or Enter to indicate that the statement continues on

the next line. For example,

s = 1 -1/2 + 1/3 -1/4 + 1/5 - 1/6 + 1/7 ...

- 1/8 + 1/9 - 1/10 + 1/11 - 1/12;

Blank spaces around the =, +, and - signs are optional, but they improve

readability.

Command Line Editing

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

and reuse statements y ou have typed earlier. For examp le, suppose you

mistakenly enter

rho = (1 + sqt(5))/2

You have misspelled sqrt. MATLAB responds with

Undefined function or variable 'sqt'.

Instead of retyping the entire line, simply press the key. T he 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 t hat beg ins w ith those

characters. You can also copy p revi ously executed statements from the

Command History. For more information, see “Command History” on page 7-7.

Following is the list of arrow an d co ntro l keys you can use in the Command

Window. If the preference you select for “Command Window K ey Binding s”
