rand (RandStream) - Uniformly distributed random numbers
Class
@RandStream
Syntax
r = rand(s,n)
rand(s,m,n)
rand(s,[m,n])
rand(s,m,n,p,...)
rand(s,[m,n,p,...])
rand(s)
rand(s,size(A))
r = rand(..., 'double')
r
= rand(..., 'single')
Description
r = rand(s,n) returns an n-by-n matrix
containing pseudorandom values drawn from the standard uniform distribution
on the open interval (0,1). The values are drawn from the random
stream s. rand(s,m,n) or rand(s,[m,n]) returns
an m-by-n matrix. rand(s,m,n,p,...) or rand(s,[m,n,p,...]) returns
an m-by-n-by-p-by-...
array. rand(s) returns a scalar. rand(s,size(A)) returns
an array the same size as A.
r = rand(..., 'double') or r
= rand(..., 'single') returns an array of uniform values
of the specified class.
Note
The size inputs m, n, p,
... should be nonnegative integers. Negative integers are treated
as 0. |
The sequence of numbers produced by rand is
determined by the internal state of the random number stream s.
Resetting that stream to the same fixed state allows computations
to be repeated. Setting the stream to different states leads to unique
computations, however, it does not improve any statistical properties.
