`scipy.interpolate._rbfinterp_pythran:_build_system_with_kernel`

Summary

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

Extended Summary

Supported prototypes:

_build_system_with_kernel(float[:,:], float[:,:], float[:], float64(float64), float, int64[:,:])

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_func : float(float) capsule: Compiled RBF kernel: maps scalar distance r to scalar value.
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.
