scipy.interpolate.BarycentricInterpolator.__call__

BarycentricInterpolator.__call__(x)[source]

Evaluate the interpolating polynomial at the points x

Parameters:

x : array-like

Points to evaluate the interpolant at.

Returns:

y : array-like

Interpolated values. Shape is determined by replacing the interpolation axis in the original array with the shape of x.

Notes

Currently the code computes an outer product between x and the weights, that is, it constructs an intermediate array of size N by len(x), where N is the degree of the polynomial.
