SignalProcessing

 GenerateUniform
 generate samples of a uniformly distributes pseudo-random signal

 Calling Sequence GenerateUniform(n, low, high)

Parameters

 n - posint, number of samples low - realcons, lower bound of the uniform distribution range hi - realcons, upper bound of the uniform distribution range

Options

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

Description

 • The GenerateUniform(n, low, high) command generates n floating-point samples of a uniformly distributed pseudo-random signal with values between the values of low and high. 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. Otherwise, a random nonnegative integer is used as the seed.

 • The SignalProcessing[GenerateUniform]  command is thread-safe as of Maple 17.
