skzeros.evaluate(z, f, w, Z)

Evaluate the rational function in barycentric form at points Z.

Parameters:

• z (1D array) – Support points of the rational function.

• f (1D array) – Values of the rational function at the support points.

• w (1D array) – Barycentric weights of the rational function.

• Z (ndarray) – Points at which to evaluate the rational function.

Returns:

r – Values of the rational function at the points Z.

Return type:

ndarray
