precision.inla_rspde {rSPDE}

Get the precision matrix of inla_rspde objects

Description

Function to get the precision matrix of an inla_rspde object created with the rspde.matern() function.

Usage

## S3 method for class 'inla_rspde'
precision(object, theta = NULL, ...)

Arguments

object

The inla_rspde object obtained with the rspde.matern() function.

theta

If null, the starting values for theta will be used. Otherwise, it must be suplied as a vector. For stationary models, we have theta = c(log(tau), log(kappa), nu). For nonstationary models, we have theta = c(theta_1, theta_2, ..., theta_n, nu).

...

Currently not used.

Value

The precision matrix.
