scipy.interpolate.pchip.antiderivative

pchip.antiderivative(nu=1)

Construct a new piecewise polynomial representing the antiderivative.

Parameters:

nu : int, optional

Order of derivative to evaluate. (Default: 1) If negative, the derivative is returned.

Returns:

bp : BPoly

Piecewise polynomial of order k2 = k + nu representing the antiderivative of this polynomial.
