scipy.interpolate.BarycentricInterpolator.set_yi

BarycentricInterpolator.set_yi(yi, axis=None)[source]

Update the y values to be interpolated

The barycentric interpolation algorithm requires the calculation of weights, but these depend only on the xi. The yi can be changed at any time.

Parameters:

yi : array_like

The y coordinates of the points the polynomial should pass through. If None, the y values will be supplied later.

axis : int, optional

Axis in the yi array corresponding to the x-coordinate values.
