Package details

Summary: Non-linear curve fitting and data analysis

Fityk is nonlinear curve-fitting and data analysis software. It allows data
visualization, separation of overlapping peaks, and least squares fitting
using standard Levenberg-Marquardt algorithm, a genetic algorithm, or
Nelder-Mead simplex method. It only knows about common bell-shaped functions
(Gaussian, Loretzian, Pearson 7, Voigt, Pseudo-Voigt) and polynomials, but
more sophisticated formulae can be easily added if necessary. It also
enables background substracting, data calibration and task automation with a
simple script language. It is being developed to analyze powder diffraction
patterns, but it can be used to fit analytical functions to any kind of data.
