Publisher review:Numerical derivative of analytic function - Calculate the numerical derivative of an analytic function with different methods. This function returns the numerical derivative of an analytic function. Of special note, is the incorporation of the "complex step-derivative" approach which offers greatly improved derivative accuracy compared to forward and central difference approximations. This is especially germain when accuracy at the level of machine precision is a concern.
