Webgradient: Estimates the gradient matrix for a simple function Description Given a vector of variables (x), and a function (f) that estimates one function value or a set of function values ( f ( x) ), estimates the gradient matrix, containing, on rows i and columns j d ( f ( x) i) / d ( x j) The gradient matrix is not necessarily square.
