NAME

       fityk - non-linear curve fitting and data analysis

SYNOPSIS

       fityk [OPTION]... [FILE]...
       cfityk [OPTION]... [FILE]...

DESCRIPTION

       This  manpage  documents  briefly  the  fityk  and  cfityk  programs  for nonlinear fitting of analytical
       functions (especially peak-shaped) to data (usually experimental data). In  other  words,  for  nonlinear
       peak separation and analysis.
       It was developed for analyzing diffraction patterns, but can be also used in other fields, since concepts
       and operations specific for crystallography are separated from the rest of the program.
       Fityk offers various nonlinear fitting methods, subtracting background, calibrating data, easy  placement
       of  peaks  and changing peak parameters, automation of common tasks with scripts, and much more. The main
       advantage of the program is a flexibility - parameters of peaks  can  be  arbitrarily  binded  with  each
       other, eg. width of peak can be an independent variable, can be the same as width of other peak or can be
       given by complicated - common for all peaks - formula.
       The program comes in two versions: fityk , the GUI version and cfityk , the command line version.
       A user manual for fityk and cfityk can be found in /usr/share/doc/fityk/html/fityk-manual.html.
