MATLAB added a new built-in function called ishermitian in 2014a. Apparently you have one of your own on the path. Type "which -all ishermitian". Locate any that do not belong to MATLAB's official toolboxes. Rename those to something else. If they do exactly the same thing as the built-in ishermitian, you're done. If they do something else, then you will need to find all uses of ishermitian in your code and change these to call whatever you named your ishermitian function to.

It would be nice to sort everything out, but since it is not your code that has the problem, I would undo my changes since they apparently broke MPT. You can undo them manually, or perhaps reinstalling MPT would be an option. Assuming there isn't an newer version that just fixes the problem, you can silence the warning with:
warning('off','MATLAB:dispatcher:nameConflict')
I have this in my startup.m file, but be careful about this because the warning does have some value--these name collisions can lead to confusion. Sometimes the old saying "ignorance is bliss" is wrong.
I would also contact the authors of MPT and ask for their advice.
