Automatically generate program logic flow chart from mfile?

I just discovered code2flow which is great for mapping out the logical flow of code, for example when debugging. However it requires you enter pseudo code, or you can run it on existing javascript or Python code. I would love if there was a similar tool that would let you make a visual representation of the logic flow of an mfile. Does this exist?

A website with name Visustin claims to have this kind of tool. I never tried it.

There is no a pure matlab code 2 flow chart generator in world. The link above is just for matlab code containing class keywords. No class matlab script will generate error info when converting code to chart.
