Normally distributed random numbers
X = randn
returns a random scalar drawn
from the standard normal distribution.
X = randn(
returns
an sz1,...,szN
)sz1
-by-...-by-szN
array of
random numbers where sz1,...,szN
indicate the size
of each dimension. For example, randn(3,4)
returns
a 3-by-4 matrix.
X = randn(___,
returns
an array of random numbers of data type typename
)typename
.
The typename
input can be either 'single'
or 'double'
.
You can use any of the input arguments in the previous syntaxes.
The sequence of numbers produced by randn
is
determined by the internal settings of the uniform pseudorandom number
generator that underlies rand
, randi
,
and randn
. You can control that shared random number
generator using rng
.
