DownloadXYmath will find the "best" curve fit using either minimum percent error or minimum total error. It can search through common equations, an exhaustive search through thousands of equations, splines, smoothed splines, or non-linear equations input by the user.
After fitting, XYmath will find roots, minima, maxima, derivatives or integrals of the curve. It will generate source code that documents and evaluates the fit in python, FORTRAN or EXCEL.
Configurable plots are created using matplotlib that are of publication quality.
