setDefaultStream (RandStream) - Set default random number stream
Syntax
prevstream = RandStream.setDefaultStream(stream)
Description
prevstream = RandStream.setDefaultStream(stream) returns
the current default random number stream, and designates the random
number stream stream as the new default to be used
by the rand, randi, and randn functions.
rand, randi, and randn all
rely on the same stream of uniform pseudorandom numbers, known as
the default stream. randi uses
one uniform value from the default stream to generate each integer
value. randn uses one or more
uniform values from the default stream to generate each normal value.
Note that there are also rand, randi, and randn methods
for which you specify a specific random stream from which to draw
values.
