Summary

0000099: IMPLEMENTED: Nonlinear least squares fitting using Levenberg-Marquardt algorithm

Description

Nonlinear fitting subroutine. Three fitting modes are supported:
* original Levenberg-Marquardt algorithm using function gradient only
* improved Levenberg-Marquardt algorithm for function with cheap O(M) gradients (less matrix inversions, more gradient calculations)
* Hessian-based improved Levenberg-Marquardt algorithm

Additional Information

Programming language

Unspecified
