Entering Statements in the Edito r/Debugger

• Reverse Case to change the case of each letter

This is useful, for example, when copying syntax from help in an M-file, where

function and variable names are distinguished by the use of uppercase. But

becauseofthat,thecodewillnotruninMATLAB.Inthisexample,thetext

was copied and pasted from the output of

help get.

V = GET(H, 'Default')

Select all of the text. Select Text > Change to Lower Case.Thetext

becomes

v = get(h, 'default')

If instead you select Reverse Case for

V = GET(H, 'Default')

thecasechangesto

v = get(h, 'dEFAULT')

Yo u can undo many of the Editor/Debugger actions listed in Edit and Text

menus. Select Ed it > Undo. You can undo multiple times in succession

until there are no remaining actions to undo. Select Edit > Redo to reverse

an undo.

help for a filename. U se

comments when testing your files or looking for errors—temporarily turn

lines of code into comments to see how the M-file runs without those lines.
