Mean of a Generalized Wendland 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_gw(dist, sigsq, phi, kappa, mu)

Arguments

`dist`	a numeric matrix representing the distance between spatial entities.
`sigsq`	the `\sigma^2` variance of the covariance function function.
`phi`	the `\phi` is the range parameter of the covariance function.
`kappa`	`\kappa \in \{0, \ldots, 3 \}`.
`mu`	`\mu` controls the smoothness of the covariance function
