curvatures_gaussian: Posterior samples of rates of change (gradients and curvatures) for the Matern kernel with \(\nu\to\infty\) producing the squared exponential kernel.

Description

For internal use only.

Usage

curvatures_gaussian(dists.1, dists.2, dists.3, z, phi, sigma2)

Value

A matrix of posterior samples for the gradient and curvatures. For internal use only.

Arguments

dists.1

distance matrix generated from coordinates

dists.2

distance of grid from coordinates

dists.3

delta = coordinate - grid

z

posterior samples of \(Z(s)\)

phi

posterior samples of \(\phi\)

sigma2

posterior samples of \(\sigma^2\)
