Gaussian anisotropic correlation function
1 2 | 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)))
|
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. |
A Gaussian anisotropic correlation matrix between points.
