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.
