scipy.interpolate.BarycentricInterpolator.__call__¶
- BarycentricInterpolator.__call__(x)[source]¶
Evaluate the interpolating polynomial at the points x
- Parameters
- xarray_like
Points to evaluate the interpolant at.
- Returns
- yarray_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.
