Hi there, I have been testing out the Levenberg-Marquardt algorithm. I've successfully coded a method in MATLAB for the example I saw on wikipedia:(adsbygoogle = window.adsbygoogle || []).push({});

f(x) = a*cos(bx)+b*sin(ax)

and this has worked well. The application I'm using the algorithm for is a system of 3 equations, however.

Does anyone have any ideas on how to implement the algorithm for multiple functions?

Thomas.
