Méthode scipy.interpolate.NdPPoly.derivative

Signature de la méthode derivative

def derivative(self, nu) 

Description

help(NdPPoly.derivative)

Construct a new piecewise polynomial representing the derivative.

Parameters
----------
nu : ndim-tuple of int
    Order of derivatives to evaluate for each dimension.
    If negative, the antiderivative is returned.

Returns
-------
pp : NdPPoly
    Piecewise polynomial of orders (k[0] - nu[0], ..., k[n] - nu[n])
    representing the derivative of this polynomial.

Notes
-----
Derivatives are evaluated piecewise for each polynomial
segment, even if the polynomial is not differentiable at the
breakpoints. The polynomial intervals in each dimension are
considered half-open, ``[a, b)``, except for the last interval
which is closed ``[a, b]``.
