# from_bernstein_basis

classmethod PPoly.from_bernstein_basis(bp, extrapolate=None)

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

  Parameters:
    bp BPoly

      A Bernstein basis polynomial, as created by BPoly

    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.
