A single header-only library for least squares optimization.

least-squares-cpp
is a header-only C++ library for unconstrained non-linear
least squares optimization using the Eigen3
library.
It provides convenient and configurable access to the following fitting algorithms:
- Gradient Descent
- Gauss Newton
- Levenberg Marquardt
Convergence and runtime behaviour can be parametrized using advanced newton step refinement
operators such as line searching or trust region methods.
- Barzilai-Borwein Method
- Armijo Backtracking
- Wolfe Backtracking
- Powell's Dogleg Method
