corr_aniso: Gaussian anisotropic correlation function

In RoyChristian/startR: Homebrewed package holding my most useful functions

Description

Gaussian anisotropic correlation function

Usage

corr_aniso(eta = 0.001, phi1 = 5, phi2 = 2.5, theta = 0,
  coords = expand.grid(x = seq(-10, 10, by = 2), y = seq(-10, 10, by = 2)))

Arguments

eta	smoothness parameters. Control how smooth the correlation function is.
phi1	decay parameter. Control the strength of the correlation between the points.
phi2	decay parameter. Control the strength of the correlation between the points.
theta	angle of the anisotropic field.
coords	matrix holding the coordinates of the points. Remember that the points must be projected if you want a correaltion matrix that make sense.

Value

A Gaussian anisotropic correlation matrix between points.
