THINSp: Thin-Plate Spline

In JonathanBradley28/CM: The Conjugate Multivariate Distribution

Description

This code computes the thin-plate spline function f(s) = s^2 log(s) for 1-dimensional spatial locations

Usage

THINSp(locs, knots, tol = 0)

Arguments

locs	n-dimensional vector of locations
knots	r-dimensional vector of knots
tol	thresholds small values of the elements of psi to be zero. Default is no threshold.

Value

psi nxr matrix of basis functions

Examples

#example two dimensional separable thin-plate spline
points1 = seq(0,1,length.out=1001)
points1=points1[2:1001]
r = 10
knots = seq(0,1,length.out=r)
G1 = THINSp(as.matrix(points1,m,1),as.matrix(knots,r,1))

G=G1 %x% G1
