compute_R_inv {templateICAr} | R Documentation |
Compute SPDE and prior precision matrices for S
Description
Compute SPDE matrices (F, G and GFinvG) and prior precision matrix for S
Usage
compute_R_inv(meshes, kappa, C1 = 1/(4 * pi), rm_extra = FALSE)
Arguments
meshes |
NULL for spatial independence model, otherwise a list of
objects of class "templateICA_mesh" containing the triangular mesh (see
make_mesh ) for each brain structure.
|
kappa |
Current estimates of SPDE parameter kappa for each latent field
|
C1 |
Constant, equal to 1/(4*pi) for a 2-dimensional field with alpha=2
|
|
If TRUE . remove extra (non-data) vertices from the mesh for greater computational efficiency
|
Value
A list containing R inverse and SPDE matrices
