Get precision matrix — get.precision.matrix • momo

get.precision.matrix allows to create a precision matrix based on a grid.

Usage

get.precision.matrix(grid, h, nu, rho, delta, matern = TRUE, diagonal = FALSE)

grid: a grid object of class momo.grid as returned by the function create.grid.
h: parameter of the matern covariance structure.
nu: parameter of the matern covariance structure.
rho: parameter of the matern covariance structure.
delta: parameter of the matern covariance structure.
matern: logical; if TRUE (default), matern covariance structure is used for simulation of environmental fields.
diagonal: logical; if TRUE, diagonal neighbours are considered in neighbouring structure. Default: FALSE.

A precision matrix.
