RandStream (RandStream) - Random number stream
Class
@RandStream
Syntax
s = RandStream('gentype')
[...]=RandStream('gentype','param1',val1,'param2',val2,...)
Description
s = RandStream('gentype') creates a random
number stream that uses the uniform pseudorandom number generator
algorithm specified by gentype.[...]=RandStream('gentype','param1',val1,'param2',val2,...) allows
you to specify optional parameter name/value pairs to control creation
of the stream. Options for gentype are given by RandStream.list.
Parameters are for RandStream are:
| Parameter | Description |
|---|
| Seed | Nonnegative scalar integer with which to initialize all streams.
Default is 0. Seeds must be an integer between 0 and
 . |
| RandnAlg | Algorithm used by randn(s, ...) to generate
normal pseudorandom values. Possible values are 'Ziggurat', 'Polar',
or 'Inversion'. |
Examples
Construct a random stream object using the combined multiple
recursive generator and generate 5 uniformly distributed values from
that stream.
stream=RandStream('mrg32k3a');
rand(stream,1,5)Construct a random stream object using the multiplicative lagged
Fibonacci generator and generate 5 normally distributed values using
the polar algorithm.
stream=RandStream('mlfg6331_64','RandnAlg','Polar');
