scipy.interpolate.BPoly.derivative¶

BPoly.derivative(nu=1)[source]¶

Construct a new piecewise polynomial representing the derivative.

Parameters:

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.

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.
