This script generates artificial spatial data using a first order spatial autoregressive process (AR1)
The process is
X(i, j) = PHI*(X(i, j-1) X(i, j 1) X(i-1, j) X(i 1, j) error
To generate a 10x10, periodic spatial pattern, with normal error distribution, and a variance of SIGMA, the command is
pattern([10, 10], PHI, SIGMA)
or equivalently,
spatialPatternAR1([10, 10], PHI, SIGMA, 1)
the same pattern, but with a rigid boundary is generated with
spatialPatternAR1([10, 10], PHI, SIGMA, 0)
Different error distributions can be used. Using the current script this can be done by extracting the generator matrix, M
M = spatialPatternAR1([10, 10], PHI, SIGMA, 1, 1)
M is a 100x100 matrix.
Then given a random vector, error (size = 100x1) with indepedent elements sampled from the required error distribution, the spatial pattern is given by
x = reshape(M * error, [10, 10])
