Generate spatial data script description:



Generate spatial data is a Matlab script for Statistics and Probability scripts design by Jon Yearsley. It runs on following operating system: Windows / Linux / Mac OS / BSD / Solaris.
Generate spatial data - Generate 1/f noise spatial data.

Publisher review:
Generate spatial data - Generate 1/f noise spatial data. 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 typespatialPattern([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 byspatialPattern([1000,1],-1) Requirements: ยท MATLAB Release: R13
