MATLAB: OnCleanup and script

oncleanuponcleanup and parfortry/catch

Hello.

I'm using a parfor loop,but sometimes I stop its execution with ctrl+c, so I would like to execute the command "matlabpool close" immediately in order not to leave the processes on. I have recommended to use onCleanup function,but I have read that I need to use it within a function and not in a script, and I've got a script, owe to that fact I wonder if I could do the same with a try/catch sentence, is it possible?

thanks!

No. try/catch cannot catch a control-c .

I would suggest just converting your script in to a function: doing so is likely to be far easier than working around the issue.

MATLAB: OnCleanup – do different things based on how you entered it.

Share a variable with the cleanup routine. Set the variable differently if the routine is exiting normally. Have the cleanup routine test the variable.

MATLAB: Close diary file on Error

TRY-CATCH is really the best solution:

diary(path_to_logfile)
try
  % all my code with output to the console, matrices written to desk, etc
catch ME
  fprintf(1, 'ERROR:\n%s\n', ME.message);
end
diary off

This is clean an efficient, and you could insert other code for cleanup also, e.g. fclose('all').
