CholeskyDecomposition: Create a parameter set specifying a LU decomposition simulation algorithm

Description

Create a parameter set describing a Cholesky (or LU) decomposition algorithm to two-point simulation, mostly for covariance or variogram-based gaussian random fields.

Usage

CholeskyDecomposition(nsim = 1, ...)

Arguments

nsim

number of realisations desired

...

further parameters, currently ignored

Value

an S3-list of class "gmCholeskyDecomposition" containing the few elements given as arguments to the function. This is just a compact way to provide further functions such as predict.gmSpatialModel() with appropriate triggers for choosing a prediction method or another, in this case for triggering LU or Cholesky decomposition simulation.

Examples

# NOT RUN {
(chols_local = CholeskyDecomposition(nsim=100, nBands=300))
## then run predict(..., pars=chols_local)
# }
