scipy.interpolate.BPoly.derivative

BPoly.derivative(nu=1)[source]

Construct a new piecewise polynomial representing the derivative.

Parameters:

nu : int, optional

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

Returns:

bp : BPoly

Piecewise polynomial of order k2 = k - nu representing the derivative of this polynomial.
