triqs.fit
Lightweight least-squares curve fitting for 1D data.
This module wraps scipy.optimize.leastsq() in a small,
plotting-friendly Fit class. A fit is
performed at construction time, the resulting object is callable
(fit(x) returns the fitted model evaluated at x) and
stringifies to a LaTeX expression – so it slots directly into
triqs.plot.mpl_interface.oplot().
Two ready-made model definitions are provided as convenience
fitter tuples: linear and
quadratic.
It is imported with the command:
>>> from triqs.fit import Fit, linear, quadratic
