gsi.CondTurningBands {gmGeostats}

Internal function, conditional turning bands realisations

Description

Internal function to compute conditional turning bands simulations

Usage

gsi.CondTurningBands(
  Xout,
  Xin,
  Zin,
  vgram,
  nbands = 400,
  tol = 1e-15,
  nsim = NULL
)

Arguments

Xout

matrix of coordinates of locations where realisations are desired

Xin

matrix of coordinates of locations of conditioning points

Zin

matrix of variables at the conditioning locations

vgram

covariogram model, of format "gmCgram"

nbands

number of bands to use

tol

tolerance for the inversion of the cokriging matrix (in case of near-singularity)

nsim

number of realisations to return

Value

an array with (npoint, nvar, nsim)-elements, being npoint=nrow(X) and nvar = nr of variables in vgram
