scipy.interpolate.PchipInterpolator.antiderivative¶

PchipInterpolator.antiderivative(nu=1)[source]¶

Construct a new piecewise polynomial representing the antiderivative.

Parameters:

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.

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.
