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.
