Noise Generators
gaussn(n)—Returns an n element vector of noise following a Gaussian probability distribution of mean 0 and standard deviation 1.
onefn(n)—Returns an n element vector of 1/f noise.
whiten(n)—Returns an n element vector of uniformly distributed white noise.
Arguments
n is an integer between 2 and the maximum array size, inclusive.
Additional Information
1/f noise is typically found in hierarchically interacting or chaotic systems, and so can be used to simulate such systems.
White noise is useful as a flat-spectrum source for filter inputs.
The sequence of the generated numbers is determined by the seed value.
The maximum array size for the noise generators depends on the hardware's processing capabilities.
