An array of normally distributed random numbers.
(y)=randn(m, n, o, p, ...)
m An integer or a vector of positive integers.
{n, o, p, ...} Positive integers.
u An array of the size specified by the inputs.

In all cases, the elements of the output array are random numbers which are normally distributed with mean zero and variance one.

If m is the only input and a integer, a matrix of size mXm is returned.

If m is the only input and a vector of positive integers, a matrix of size m is returned.

If number of inputs is more than one, all of them must be positive integers. In this case, the size of the output is [m, n, o, p, ...] .
