echo
controls the echoing of M-files during execution. Normally, the commands in M-files do not display on the screen during execution. Command echoing can be enabled for debugging, or for demonstrations, allowing the commands to be viewed as they execute.
echo
behaves slightly differently, depending on whether a script file or a function file is being considered. For script files, the use of echo
is simple; echoing can be either on
or off
, in which case any script used is affected:
echo
on
turns on the echoing of commands in all script files.echo
off
turns off the echoing of commands in all script files.echo
, by itself, toggles the echo state.echo
is more complicated. If echo
is enabled on a function file, the file is interpreted, rather than compiled, so that each input line can be viewed as it is executed. Since this results in inefficient execution, use echo
only for debugging.
