Dear All,
I'm looking for a Levenberg-Marquadt implementation for fitting multiple
functions at multiple points.
Means there are n functions f1(a, x)..fn-1(a, x) and multiple
m-dimensional x-points and matching result points for every function.
Parameter vector a is to be determined.
C++ or java or both would be fine.
What I found so far is only intended to fit a single function, e.g.
http://www.idiom.com/~zilla/Computer/Javanumeric/index.html
Preferable would be if the package only needs the least-square-error
function to be implemented
and maybe the matching gradient function -- but I will anyway
approximate this.
Peter
