Signature de la méthode add_xi

def add_xi(self, xi, yi=None) 

Description

add_xi.__doc__

        Add more x values to the set to be interpolated

        The barycentric interpolation algorithm allows easy updating by
        adding more points for the polynomial to pass through.

        Parameters
        ----------
        xi : array_like
            The x coordinates of the points that the polynomial should pass
            through.
        yi : array_like, optional
            The y coordinates of the points the polynomial should pass through.
            Should have shape ``(xi.size, R)``; if R > 1 then the polynomial is
            vector-valued.
            If `yi` is not given, the y values will be supplied later. `yi` should
            be given if and only if the interpolator has y values specified.
