Saving

Use Saving preferences to s pecify how often to automatically save the

history.m file during a M ATLAB session.

Save History File On Quit

Select this option to save the history.m file when you end the MATLAB

session. If the sessio n does not end via a normal termination, that is, via the

exit or quit functions, File > Exit MA TLAB, or the MATLAB desktop Close

box, the history file is not saved for that s ession.

Save After n Commands

Select this option to save the history.m file after n statements are added to

the file. For example, when you select the option and set

n to 10, after every

10 statements are added, the history file is automatically saved. Use this

option if you don’t want to risk losing entries to the saved history because of

an abnormal termination, such as a power failure.

Don’t Save History File

Select this option if you do not want to save the history.m file. Thi s feature is

useful when multiple users share the same machine and do n ot want other

users to view the statements they have run.

Note that any entries already in the

history.m fi le remain. Prior to setting

this preference, you might want to remove any existing entries. Follow the

instructions in “Deleting Entries from the Command History Window” on

page 3-57.
