The script generates spatial data with a ...

The script generates spatial_data with a scale-invariant power spectrum (1/f noise) and a normal error distribution.
The spectral density of the data is proportional to f^beta, where f is the frequency and BETA is the spectral exponent (BETA=0 is white noise, BETA=-2 is brown noise).
To generate Brown noise on a 10x10 grid you type
spatialPattern([10, 10], -2)
which gives a 10x10 matrix containihng the data.
1/f noise is not stationary, and so doesn't have a well defined variance. A variogram of the data show variance linearly increasing with increasing lag.
Time series data can also be generated. For example, a pink noise time series of lenth 1000 is produced by
spatialPattern([1000, 1], -1)

• MATLAB Release: R13
