About:
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 knows about many functions (mostly bell-shaped, like Gaussian, Loretzian, Pearson 7, Voigt, Pseudo-Voigt, and Doniach-Sunjic) and user-defined functions can be easily added. 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 is also used in chromatography, photoluminescence, infrared, and Raman spectroscopy, and can be used to fit analytical functions to any kind of data. The most similar program to Fityk is probably PeakFit.
