scipy.interpolate.PchipInterpolator.from_power_basis

classmethod PchipInterpolator.from_power_basis(pp, extrapolate=None)

Construct a piecewise polynomial in Bernstein basis from a power basis polynomial.

Parameters

ppPPoly

A piecewise polynomial in the power basis

extrapolatebool 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.
