gamma1n2.mcov2: Cross-covariance terms for the posterior distribution of wombling measures for Matern \(\nu=5/2\), the squared exponential kernel.

Description

For internal use only. Performs one-dimensional quadrature using integral as a limit of a sum.

Usage

gamma1n2.mcov2(coords, t, u, s0, phi)

Value

A matrix of cross-covariance terms. For internal use only.

Arguments

coords

coordinates

t

value of t

u

vector of u

s0

starting point on curve \(s_0\)

phi

posterior sample of \(\phi\)
