SpatialFloor (version 1.1.0)

iso_spatial_exp: Isotropic spatial simulation by exponential function

Description

This function load grid floor and generate the var-cov matrix via exponential function

Usage

iso_spatial_exp(dist.matrix, nugget, sill, ranges)

Arguments

dist.matrix

the a distance matrix generate from spatial_dist function

nugget

the nugget value of the var-cov function

sill

the sill(variance, sigma^2) of the var-cov function

ranges

the range value of var-cov function

Value

A matrix of var-cov matrix

Examples

# NOT RUN {
D = spatial_dist(expand.grid(1:5, 1:5))
iso_spatial_exp(D, 0, 3, 1)
# }
