def antiderivative(self, nu=1) 

Description

antiderivative.__doc__

        Construct a new piecewise polynomial representing the antiderivative.

        Antiderivative is also the indefinite integral of the function,
        and derivative is its inverse operation.

        Parameters
        ----------
        nu : int, optional
            Order of antiderivative to evaluate. Default is 1, i.e., compute
            the first integral. If negative, the derivative is returned.

        Returns
        -------
        pp : PPoly
            Piecewise polynomial of order k2 = k + n representing
            the antiderivative of this polynomial.

        Notes
        -----
        The antiderivative returned by this function is continuous and
        continuously differentiable to order n-1, up to floating point
        rounding error.

        If antiderivative is computed and ``self.extrapolate='periodic'``,
        it will be set to False for the returned instance. This is done because
        the antiderivative is no longer periodic and its correct evaluation
        outside of the initially given x interval is difficult.
