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.
