scipy.interpolate.BarycentricInterpolator.__init__

BarycentricInterpolator.__init__(xi, yi=None)

Construct an object capable of interpolating functions sampled at xi

The values yi need to be provided before the function is evaluated, but none of the preprocessing depends on them, so rapid updates are possible.

Parameters :

xi : array-like of length N

The x coordinates of the points the polynomial should pass through

yi : array-like N by R or None

The y coordinates of the points the polynomial should pass through; if R>1 the polynomial is vector-valued. If None the y values will be supplied later.
