getMatCov {GPvecchia} | R Documentation |
This function takes the entire covariance matrix and creates a matrix of covariances based on the vecchia approximatino object
getMatCov(V, covariances, factor = FALSE)
V |
the object returned by vecchia_specify |
covariances |
The full covariance matrix or a covariance function |
factor |
True if we are passing a factor of a matrix |
matrix of size n x (m+1) with only those elements that are used by the incomplete Cholesky decomposition
