This is an experimental function, implementing a crucially needed feature, which is for an unknown reason not part of Matlab.
If you use it and it does not work: Please do not downgrad immediatly, but leave a comment. Since I need this functionality for my own projects, I am grateful for constructive comments.

Currently, in Matlab it is not possible to check whether there are available workers to run a parfor loop. It is able to check it for stuff to be run via parfeval, but not for stuff to be run via parfor.

The problem is that, when a function executes a parfor loop, but it is terminated early (e.g. via Ctrl-C), then the spawned workers for the parfor loop are not terminated. Instead they continue to run on. Since a too-long running parfor loop is often the reason why one aborts a program via Ctrl-C, this scenario happens easily.

Therefore, this function is crucially needed but for a strange reason not part of Matlab
