Signature de la méthode derivative

def derivative(self, nu) 

Description

derivative.__doc__

        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]``.
