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.
