Fityk is a program for nonlinear fitting of analytical functions
|
|
(especially peak-shaped) to data. It can also be used 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 a graphical interface (and also command line
|
|
interface), various optimization methods (standard Marquardt
|
|
least-squares algorithm, Genetic Algorithms, Nelder-Mead simplex),
|
|
equality constraints, modeling error of x coordinate of points
|
|
(eg. zero-shift of instrument), handling series of datasets,
|
|
automation of common tasks with scripts, and more.
