Fityk 0.98is a Windows program for nonlinear fitting of analytical functions to data.

>:(   (Suddenly once "Free for All" software costs way too much.)

Fityk [fi:tik] is a program for data processing and nonlinear curve fitting.

Although it is primarily used...

    by scientists who analyse data from powder diffraction, chromatography, photoluminescence and photoelectron spectroscopy, infrared and Raman spectroscopy, and other experimental techniques,

    to fit peaks – bell-shaped functions (Gaussian, Lorentzian, Voigt, Pearson VII, bifurcated Gaussian, EMG, Doniach-Sunjic, etc.),

... the program can be used for any task that requires fitting a curve to 2D (x,y) data.


In an attempt to make this software self-sustaining and actively developed in the future, new binaries are available to subscribers only!

Versions 0.9.8 and older are free: for Windows and Linux (Ubuntu PPA and RPMs from OBS).

Source code: GitHub

Version 1.2.1 was released on 2012-11-05 (changelog). New version notifications are delivered via email and feeds.
