Howto ... Matlab

... batch processing? =

To call Matlab from the command line or a shell script and have it execute a command or a Matlab script call:

matlab -nojvm -nosplash -r [x,y,z]=script -logfile script.log > /dev/null

This must be called in a directory that contains a file script.m. Whatever Matlab usually dumps to its console ends up in the file script.log. To make sure it does not show up in your script output stdout is redirected to /dev/null. The [x,y,z]= part is only necessary if your script returns results which you would want to use somehow.

IMPORTANT: make sure your script contains an 'exit;' as last command! Otherwise this Matlab instance would remain running which might end up with really nasty performance results in a loop statement. If a bunch of matlab scripts are to be executed, compile a master .m-file which calls them (and is the only one that contains the 'exit;'). This way Matlab is not closed and restarted for each script which might gain a significant performance gain.
