scipy.interpolate.BPoly.derivative

BPoly.derivative(self, nu=1)[source]

Construct a new piecewise polynomial representing the derivative.

Parameters
nuint, optional

Order of derivative to evaluate. Default is 1, i.e. compute the first derivative. If negative, the antiderivative is returned.

Returns
bpBPoly

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