I am looking for a C# implementation of the Levenberg–Marquardt algorithm for non-linear least squares fit.

Answer 1

Levenberg-Marquardt.NET by Krzysztof Kniaz has worked very well for me.

Answer 2

You might want to try csmpfit. It is open source.

Update:

The project has been moved to GitHub at https://github.com/cureos/csmpfit.

Answer 3

Here is an explanation article plus C# code:

It uses Math.NET Numerics for linear algebra to simplify the Levenberg-Marquardt algorithm.
