precision.inla_rspde: Get the precision matrix of 'inla_rspde' objects

In rSPDE: Rational Approximations of Fractional Stochastic Partial Differential Equations

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.
