I want to make a program that solves a non linear system with five equations and five unknowns for each pixel of my picture data (one system by pixel). I use broyden function and for certain pixel it works good but for certain I have an error: "MAXITS exceeded in broydn.". I think that the solutions do not converge. But I want to know how to make the computation for all pixels even if I have an error. I think that I must use the exception but I don't know how ? I think that a solution would be to programm the newton function but it seems to me difficult... Thans in advance
