Fityk is a program for nonlinear fitting of analytical functions
|
|
(especially peak-shaped) to data (usually experimental data). There are
|
|
also people using it only to display data or to remove baseline from
|
|
data.
|
|
|
|
It is reported to be used in crystallography, chromatography,
|
|
photoluminescence, infrared and Raman spectroscopy and other fields.
|
|
|
|
Fityk knows about common peak-shaped functions (Gaussian, Lorentzian,
|
|
Voigt, Pearson VII, bifurcated Gaussian, EMG, Doniach-Sunjic, etc.) and
|
|
polynomials. It also supports user-defined functions.
|
|
|
|
Fityk offers intuitive graphical interface (and also command line
|
|
interface), variouse optimization methods (standard Marquardt
|
|
least-square algorithm, Genetic Algorithms, Nelder-Mead simplex),
|
|
equality constraints, modelling error of x coordinate of points (eg.
|
|
zero-shift of instrument), handling series of datasets, automation of
|
|
common tasks with scripts, and more.
