C# Class Accord.Math.Optimization.GaussNewton

Gauss-Newton algorithm for solving Least-Squares problems.

This class isn't suitable for most real-world problems. Instead, this class is intended to be use as a baseline comparison to help debug and check other optimization methods, such as LevenbergMarquardt.
