These minimization problems arise especially in least squares curve fitting. The LMA interpolates between the Gauss–Newton algorithm (GNA) and the ...

You have to provide the Jacobian (matrix o partial derivatives) and the function [original system]. This form a system of linear equations of type Ax=b. To solve the linear system, you call your Gauss-Seidel routine to solve it iteratively.
