Precision matrix for Whittle-Matérn fields
Description
Computes the precision matrix for all vertices for a Whittle-Matérn field.
Usage
spde_precision(kappa, tau, alpha, graph, BC = 1, build = TRUE)
Arguments
kappa |
Range parameter. |
tau |
Precision parameter. |
alpha |
Smoothness parameter (1 or 2). |
graph |
A |
BC |
Set boundary conditions for degree=1 vertices. BC =0 gives Neumann boundary conditions and BC=1 gives stationary boundary conditions. |
build |
If |
Value
Precision matrix or list.
