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/fitykhelp.html.
