inla.spde.precision(...)

## S3 method for class 'inla.spde2'
inla.spde.precision(spde,
                    theta = NULL,
                    phi0 = inla.spde2.theta2phi0(spde, theta),
                    phi1 = inla.spde2.theta2phi1(spde, theta),
                    phi2 = inla.spde2.theta2phi2(spde, theta), ...)
inla.spde2.precision(spde,
                     theta = NULL,
                     phi0 = inla.spde2.theta2phi0(spde, theta),
                     phi1 = inla.spde2.theta2phi1(spde, theta),
                     phi2 = inla.spde2.theta2phi2(spde, theta), ...)

## For deprecated inla.spde1 models:
## S3 method for class 'inla.spde1'
inla.spde.precision(spde, ...)
inla.spde1.precision(spde, ...)
