Non-linear curve fitting and data analysis
Fityk is nonlinear curve-fitting and data analysis software. It supports 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 common bell-shaped functions (Gaussian, Lorentzian, Pearson 7, Voigt, Pseudo-Voigt) and polynomials, but more sophisticated formulae can be added if needed. 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 can be used to fit analytical functions to any kind of data.
