FIT2_1-5.zip FIT2 1.5 (1994-02-11) - FIT2 a non-linear least-squares fitting program. The algorithm uses the Marquardt method to find the best fit. It opens a pipe to gnuplot to plot data and the attempted fit. Includes binaries and source code. (LSQRFT15.ZIP) [Detailapplication/zip 277.17 KB 2023/04/06
