scipy.interpolate.PiecewisePolynomial.extend

PiecewisePolynomial.extend(xi, yi, orders=None)

Extend the PiecewisePolynomial by a list of points

Parameters:

xi : array_like

A sorted list of x-coordinates.

yi : list of lists of length N1

yi[i] (if axis == 0) is the list of derivatives known at xi[i].

orders : int or list of ints, optional

A list of polynomial orders, or a single universal order.
