source: /scipy/interpolate/_rbfinterp_xp.py:151

Signature

def _build_system(y, d, smoothing, kernel, epsilon, powers, xp)

Summary

Build the system used to solve for the RBF interpolant coefficients.

Parameters

y : (P, N) float ndarray: Data point coordinates.
d : (P, S) float ndarray: Data values at y.
smoothing : (P,) float ndarray: Smoothing parameter for each data point.
kernel : str: Name of the RBF.
epsilon : float: Shape parameter.
powers : (R, N) int ndarray: The exponents for each monomial in the polynomial.

Returns

lhs : (P + R, P + R) float ndarray: Left-hand side matrix.
rhs : (P + R, S) float ndarray: Right-hand side matrix.
shift : (N,) float ndarray: Domain shift used to create the polynomial matrix.
scale : (N,) float ndarray: Domain scaling used to create the polynomial matrix.
