function stream = getGlobalStream

%RANDSTREAM.GETGLOBALSTREAM Get the current global random number stream.

%   STREAM = RandStream.GETGLOBALSTREAM returns the current global random

%   number stream, i.e., the stream that the RAND, RANDI, and RANDN functions

%   draw values from.

%

%   RAND, RANDI, and RANDN all rely on the same stream of uniform pseudorandom

%   numbers, known as the global random number stream.  RAND draws one value

%   from that stream to generate each uniform value it returns;  RANDI draws

%   one uniform value from that stream to generate each integer value it

%   return; and RANDN draws one or more uniform values to generate each normal

%   value it returns.  Note that there are also RAND, RANDI, and RANDN methods

%   for which you specify a specific random stream from which to draw values.

%

%   The RNG function is a shorter alternative for many uses of

%   RANDSTREAM.getGlobalStream.

%

%   See also RNG, RANDSTREAM, RANDSTREAM.SETGLOBALSTREAM,

%            RANDFUN/RAND, RANDFUN/RANDN, RANDFUN/RANDI.
