% VL_TWISTER() is essentially equivalent to MATLAB native RAND()
% when using the Twister random number generator. VL_TWISTER(),
% VL_TWISTER(M,N,P,...) and VL_TWISTER([M N P ...]) are equivalent
% to RAND(), RAND(M,N,P,...) and RAND([M N P ...]) respectively.
%
% The state of the random generator can be seeded by
% VL_TWISTER('STATE', X), where X is a DOUBLE scalar (this is
% equivalent to RAND('TWISTER', X)). The state can be read by
% VL_TWISTER('STATE') (equivalent to RAND('TWISTER')) and set by
% VL_TWISTER('STATE', STATE) (equivalent to RAND('TWISTER',
% STATE)). Here STATE is a vector of 625 elements of class
% UINT32. Finally VL_TWISTER('STATE',KEY) seeds the generator by a
% vector of DOUBLE of length not greater than 624.
%
% VL_TWISTER() is slightly faster than RAND(). Moreover it can be
% used to control the state of the random number generator used by
% all VLFEAT functions.
