scipy.interpolate.BPoly.derivative

BPoly.derivative(nu=1)

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.
