stModel.matrices

This function computes all the matrices needed to build
the precision matrix for spatio-temporal model,
as in Lindgren et. al. (2023)

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)
<https://www.idescat.cat/sort/sort481/48.1.1.Lindgren-etal.pdf>.
Details are provided in the available vignettes and from the URL bellow.
