scipy.interpolate.BPoly.

BPoly.derivative(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.
