Are you trying to cancel the operation part way through (like with Ctrl+C)? Or are you trying to duplicate functionality like:
for ix=1:10
if ix == 6
break
end
end
If the latter, keep in mind (from the documentation of parfor): "Note: Because of independence of iteration order, execution of parfor does not guarantee deterministic results." The reason parfor cannot contain break or return is because of this independence of iteration order.
