If this is really better than fminsearch that ships with basic MATLAB, then proposed it as an improvement to TMW. TMW might not be in favor of posting their code having only a few bytes of different code. Please remove this submission.

This is a copy of fminsearch, but the help has not been fixed to show that you should use fminsearch2. (I don't know if there are any legal issues with submitting MathWorks code on the file exchange.)

I did not get that deeply into the code, merely tried a couple of various scalings of the Rosenbrock function. For most of my tests, fminsearch2 took exactly the same amount of function evals and iterations as did fminsearch. Some additional testing did find one case where fminsearch2 was 30% more efficient. I stopped at that point.
