Summary

Construct the coefficients needed to evaluate the RBF.

Parameters

x : (Q, N) float ndarray: Evaluation point coordinates.
y : (P, N) float ndarray: Data point coordinates.
kernel : str: Name of the RBF.
epsilon : float: Shape parameter.
powers : (R, N) int ndarray: The exponents for each monomial in the polynomial.
shift : (N,) float ndarray: Shifts the polynomial domain for numerical stability.
scale : (N,) float ndarray: Scales the polynomial domain for numerical stability.

Returns

: (Q, P + R) float ndarray
