Gnuplot is a portable commandline driven graphing utility for Linux, OS2, MS Windows, OSX, VMS, and many other platforms. The source code is copyrighted but freely distributed (i. e.you dont have to The fit command can fit a userdefined function to a set of data points (x, y) or (x, y, z), using an implementation of the nonlinear leastsquares (NLLS) MarquardtLevenberg algorithm. Any userdefined variable occurring in the function body may serve as a fit parameter, but the return type of Nonlinear curve fitting with gnuplot.

Maybe gnuplot users are not so interested in plotting functions, except for your Math homework (or some special purpose which I don't know), but this is extremely useful for a parameterfitting to experimental data, namely a leastsquares fitting.
Nonlinear curve fitting using GNU plot Metrology is a very satisfying occupation but there will be roadblocks along the way. For some of us curve fitting is easy so long as we have a standard software package that solves our problem.
