Eigen - Levenberg Marquardt algorithm: invalid template arguments on definition of permutation

I'm trying to use the Eigen implementation of Levenberg Marquardt algorithm on a Android application. In order to use Eigen, I'm using Android NDK and jni. I've already tested Eigen with simple calculations (like matrix creation and vector sums) and it works perfectly. However, when I tried to use...

Non-linear Least Squares Optimization Library for C [closed]

I'm looking for a library in C that will do optimization of an objective function (preferrably Levenberg-Marquardt algorithm) and will support box constraints, linear inequality constraints and non-linear inequality constraints. I've tried several libraries already, but none of them do employ the...
