 GenerateGaussian - Maple Help

SignalProcessing

 GenerateGaussian
 generate samples of a Gaussian random signal Calling Sequence GenerateGaussian(n, mean, stddev) Parameters

 n - posint, number of samples mean - realcons, mean of the Gaussian distribution stddev - realcons, standard deviation of the Gaussian distribution Options

 • container : Array, predefined Array for holding results
 • seed : nonnegint, seed for the pseudo-random number generator Description

 • The GenerateGaussian( n, mean, stddev, seed ) command generates n floating-point samples for a random signal with a Gaussian distribution of mean mean and with standard deviation stddev. The results are returned in an Array with datatype float.
 • If the container=C option is provided, then the results are put into C and C is returned. With this option, no additional memory is allocated to store the result. The container must be an Array of size n having datatype float.
 • If the seed option is provided, the given value is used as the seed for the pseudo-random number generator. • The SignalProcessing[GenerateGaussian] command is thread-safe as of Maple 17. Examples
