I would like to follow the run on a progress bar of a cycle. In case of simple for-loop is easy, but whatif I use parfor?

What do you mean by a cycle? If you mean the loop that is actually parallel then a progress bar will not work with this, although there are some on File Exchange that will, though only really if there are sufficiently more iterations than there are cores.
is the one I use for this purpose, though it does lead to a load of warnings in scenarios where previous objects of the class are not properly deleted.

You can implement this with a data queue. See a waitbar example here:
