antiderivative
(nu=1)[source]¶ 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.
