scipy.interpolate.PchipInterpolator.from_power_basis¶

classmethod PchipInterpolator.from_power_basis(pp, extrapolate=None)[source]¶

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

Parameters:

Parameters:	pp : PPoly A piecewise polynomial in the power basis 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.

A piecewise polynomial in the power basis

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.
