GSTLEARN_EXPORT int krigingSPDE ( Db dbin,
Db dbout,
Model model,
bool  flag_est,
bool  flag_std,
const AMesh mesh,
int  useCholesky,
SPDEParam  params,
int  nbMC,
int  seed,
bool  verbose,
bool  showStats,
const NamingConvention namconv 
)

Perform the estimation by KRIGING under the SPDE framework

Parameters
dbinInput Db (must contain the variable to be estimated)
dboutOutput Db where the estimation must be performed
modelModel definition
flag_estTrue for the estimation
flag_stdTrue for the standard deviation of estimation error
meshMesh description (optional)
useCholeskyDefine the choice regarding Cholesky
paramsSet of parameters
nbMCNumber of Monte-Carlo simulations used for variance calculation
seedSeed used for the Random Number generator
verboseVerbose flag
showStatsShow statistics for Linear Operations
namconvNaming convention
Returns
Error return code
Remarks
You can provide an already existing mesh. Otherwise an optimal mesh will be created
internally: one per structure constituting the Model for Kriging.
Each mesh is created using the Turbo Meshing facility... based on an internal grid.
This internal grid is rotated according to the rotation of the structure. Its mesh size
is derived from the range (per direction) by dividing it by the refinement factor.
Note that switching 'flag_std' to ON implies that 'flag_est' is ON.
