Mean of a (Matern) covariance function (Internal use)

Description

This is an auxiliary function for internal use. It helps to numerically integrate a covariance function evaluated at a grid of points within a polygon and speed-up the computations.

Usage

aux_matern(dist, sigsq, phi, nu)

Arguments

`dist`	a numeric matrix representing the distance between spatial entities.
`sigsq`	the `\sigma^2` parameter from the Matern covariance function.
`phi`	the `\phi` parameter from the Matern covariance function, controls the range of the spatial dependence.
`nu`	the `\nu` parameter from the Matern covariance function, controls the differentiability of the process.
