Analyse Krigeante a covariance discretisee

Description

Analyse Krigeante a covariance discretisee

Usage

anakexp3D(dbgrid, covref, model, neigh.ver=0, neigh.hor=0,
	flag.sym = TRUE, nugget=0, nfeq = 0, dbg.ix = -2, dbg.iy  = -2,
	radix = "AnaKexp", modify.target = db.locmod())

Arguments

dbgrid

The db-class 3-D grid structure containing the data file

covref

The vector containing the discretized covariance of the total variable along the vertical axis. This vector must have an odd dimension.

model

Model used to define the lateral structure of the target variable

neigh.ver

Radius of the neighborhood along the vertical (in number of pixels)

neigh.hor

Radius of the neighborhood along the horizontal (in number of pixels). In 3-D, the radius neighborhood is the same along X and Y.

flag.sym

If TRUE, the discretized covariance is symmetrized when used in the kriging system

nugget

Nugget Component added to the L.H.S. matrix

nfeq

Number of drift equations in the kriging system. It must be 0 (stationary) or 1 (intrinsic)

dbg.ix

Rank of the trace for variogram debugging (between 0 and nx-1). The index -1 corresponds to the underlying variable. When this index is set to a valid value, the covariance map is dumped on a local file called "Vario.dat".

dbg.iy

Rank of the trace for variogram debugging (between 0 and ny-1). The index -1 corresponds to the underlying variable. When this index is set to a valid value, the covariance map is dumped on a local file called "Vario.dat".

radix

Radix of the name given to the variables storing the results in the db-class.

modify.target

Decides whether or not the newly created variables will have their locator defined or not. For more information, see db.locmod.

Value

The data db-class where the extracted variable has been added.
