scipy.interpolate.PPoly.from_spline¶

classmethod PPoly.from_spline(tck, extrapolate=None)[source]¶

Construct a piecewise polynomial from a spline

Parameters:

Parameters:	tck A spline, as returned by `splrep` or a BSpline object. extrapolate : bool or ‘periodic’, optional If bool, determines whether to extrapolate to out-of-bounds points based on first and last intervals, or to return NaNs. If ‘periodic’, periodic extrapolation is used. Default is True.
