Hi,
There are certain functions I don't want to execute in parallel, and I would like to throw an error if they are. Is there anyway to know if I am inside a parfor?
Thanks Joan

You can check to see if you are currently running on a worker (aka running in parallel) by using the following commands.
parfor ii = 1:2
job = getCurrentJob;
if isempty(job)
display('not running in parallel')
else
display('running in parallel')
end
end
If you are not running in parallel, the function should return an empty. If you are running in parallel, it will return a job object corresponding to the job you are inside.

With your code I was able to write this function which works great:
function ip = inParallel()
job = getCurrentJob();
ip = ~isempty(job);
end
Thanks!
