classmethod CubicSpline.from_spline(tck, extrapolate=None)[source]#

Construct a piecewise polynomial from a spline

Parameters

tck: A spline, as returned by splrep or a BSpline object.
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.
