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 is 1, i.e. compute the first derivative. If negative, the antiderivative is returned.
Returns: bp : BPoly
Piecewise polynomial of order k - nu representing the derivative of this polynomial.
