spde2precision

Creates a precision matrix as a sparse matrix object.
For general code look at the functions in the INLA package.

Prepare objects to implement models over spatial and
spacetime domains with the 'INLA' package (<https://www.r-inla.org>).
These objects contain data to for the 'cgeneric' interface in
'INLA', enabling fast parallel computations.
We implemented the spatial barrier model, see Bakka et. al. (2019)
<doi:10.1016/j.spasta.2019.01.002>, and some of the spatio-temporal
models proposed in Lindgren et. al. (2023)

Details are provided in the available vignettes and from the URL bellow.
