Re: [eigen] Non linear equations solver

[ Thread Index | Date Index | More Archives ]

I implemented a primitive Levenberg-Marquardt and Powell's dogleg minimizer using Eigen:

They work on simple problems but are not industrial strength. However, I would be happy to help with extending these if necessary.

Hello all

I would like to ask you how to focus non linear equations solving in Eigen. I mean:

1. Is there somebody working on it now?

2. Did you know libraries or code to do it that could match well with Eigen? (including similar license)
I have seen something about DASPK (for DAE solving)

3. The last solution I have is to port the solver I use that comes in a 90% from Numerical Recipes source. But I would prefer to include something with a LGPL like license.
