But i disagree that some LM implementation has nothing to do in eigen : as most nonlinear algorithm, it's mostly "do a lot of linear operations in loops". Very much in the topic of eigen.I have often thought about using Eigen for my own scientific computing projects, but each time I have been deterred by what I consider its enormous size (don't even get me started about Boost). To include a nonlinear optimizer in it would just make things that much worse. I know there are a lot of projects out there that use Eigen only for fixed size 3x3 or 4x4 matrices for use in graphics, or some that use it for basic matrix multiplication/inversion and such. Including LM would be far outside the realm of relevance for them.
