Supported prototypes:

• _evaluate(float[:,:], float[:,:], str, float, int[:,:], float[:], float[:], float[:,:])

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.

coeffs : (P + R, S) float ndarray

Coefficients for each RBF and monomial.

Returns

(Q, S) float ndarray

Evaluate the RBF interpolant at x.

Examples

See :

Local connectivity graph

Hover to see nodes names; edges to Self not shown, Caped at 50 nodes.

Using a canvas is more power efficient and can get hundred of nodes ; but does not allow hyperlinks; , arrows or text (beyond on hover)

SVG is more flexible but power hungry; and does not scale well to 50 + nodes.

All aboves nodes referred to, (or are referred from) current nodes; Edges from Self to other have been omitted (or all nodes would be connected to the central node "self" which is not useful). Nodes are colored by the library they belong to, and scaled with the number of references pointing them
