Matern covariance function (scalar - generic)

Description

Computing the Matern covariance function for a single distance measure, addapted from geoR.

Usage

single_matern(d, sigsq, phi, nu)

Arguments

d	a scalar representing the distance on which it is desired to evaluate the covariance function.
sigsq	the σ^2 parameter from the Matern covariance function.
phi	the φ parameter from the Matern covariance function, controls the range of the spatial dependence.
nu	the ν parameter from the Matern covariance function, controls the differentiability of the process.

Value

a scalar representing the (matern) covariance between two observations d apart of each other.
