16 Feb 2009 Adaptive Robust Numerical Differentiation Numerical derivative of an analytically supplied function, also gradient, Jacobian & Hessian Author: John D'Errico

This worked better than fminsearch when used as a damped newton method for finding a root with extremely high sensitivity. fminsearch was overly slow, and often overshot the root, even though the tolerance was high, and fzero didn't work at all. Derivest was fast.
This is the second time I've used great code from John D'Erico.
