Overview

README for ufit

ufit is a universal scattering data fitting package for use in noninteractive scripts, and with a graphical user interface.

It handles complex fitting functions by combining them from pre-defined "model" objects and handling parameter constraints and interdependencies well.

Fitting is done by one of several backends:

  • lmfit (L-M leastsq that allows parameter constraints)
  • minuit (pyminuit 1 or 2)
  • scipy (basic L-M leastsq from scipy.optimize)

Results can be easily plotted and further processed. Plotting is handled by matplotlib.

The GUI uses PyQt 4.
