FNFIT: An East-to-Use, Arbitrary Function-to-Data Fitting Routine (A user's Manual)

Abstract

The program FNFIT uses both steepest gradient, and chi-square minimization searches to fit a user-chosen, arbitrary (including nonlinear) function to a set of input data points. Options are included to allow control of the search for particularly pathological functions, making the program quite versatile. However, the program can also be run without the options, providing an easy-to-learn-and-use tool for the pedestrian.
