I have used PC-MATLAB for data analysis etc. for a long time, but I have not noticed before, that it lacks a nonlinear equation solver. It would be rather straightforward to write a M- or MEX-file for this for example on the basis of Numerical Recipes. But it's so commonly needed, that I decided to make a query before I start to write one. So: Do you know, if there exists (a public domain or comm.) M- or MEX-function, which finds one or more N-dimensional solution vectors x such that F(x) = 0 Where F is the N-dimensional vector-valued function whose components are the individual equations to be satisfied simultaneously.
