pwtools.num.Fit1D

class pwtools.num.Fit1D(x, y)

Bases: object

Base class for 1D data fit/interpolation classes (Spline, PolyFit1D). It provides get_min(), get_max(), get_root(), is_mono().

The assumed API is that the __call__ method has a kwd der which causes it to calculate derivatives, i.e. __call__(x, der=1) is the first deriv.

__init__(x, y)

Methods

get_max([x0, xab])	Convenience method.
get_min([x0, xab])	Return x where y(x) = min(y) by calculating the root of the fit's 1st derivative (by calling self(x, der=1)).
get_root([x0, xab])	Return x where y(x) = 0 by calculating the root of the fit function.
is_mono()	Return True if the curve described by the fit function f(x) is monotonic.
