rand

Generate quasirandom points from stream

Syntax

rand
rand(q,n)
rand(q)
rand(q,m,n)
rand(q,[m,n])
rand(q,m,n,p,...)
rand(q,[m,n,p,...])


Description

rand returns a matrix of quasi-random values and is intended to allow objects of the qrandstream class to be used in code that contains calls to the rand method of the MATLAB^® pseudo-random randstream class. Due to the multidimensional nature of quasi-random numbers, only some syntaxes of rand are supported by the qrandstream class.

rand(q,n) returns an n-by-n matrix only when n is equal to the number of dimensions. Any other value of n produces an error.

rand(q) returns a scalar only when the stream is in one dimension. Having more than one dimension in q produces an error.

rand(q,m,n) or rand(q,[m,n]) returns an m-by-n matrix only when n is equal to the number of dimensions in the stream. Any other value of n produces an error.

rand(q,m,n,p,...) or rand(q,[m,n,p,...]) produces an error unless p and all following dimensions sizes are equal to one.

Examples

Generate the first 256 points from a 5-D Sobol sequence:

q = qrandstream('sobol',5);
X = rand(q,256,5);
