4. Run the DQuickLTFit executable.

About

DQuickLTFit software is written in C++ (Qt-framework) and has implemented the MPFIT C library [1] for solving the non-linear least-square problem using the Levenberg-Marquardt algorithm. MPFIT was ported from MINPACK-1 library [2,3].

The disclaimer of MPFIT library can be found here.
