help diary

DIARY Save text of MATLAB session.

DIARY file_name causes a copy of all subsequent terminal input

and most of the resulting output to be written on the named

file. DIARY OFF suspends it. DIARY ON turns it back on.

DIARY, by itself, toggles the diary state.

Use the functional form of DIARY, such as DIARY('file'),

when the file name is stored in a string.
