Re: RandomArray from user defined distribution?

The documentation is pretty clear.

<<RandomArray`DiscreteDistributions`  (* load the package*)
mu=3.7;                                              (* set mu to your
desired value *)
poi=PoissonDistribution[mu];                (* define a poission
distribution at mu *)
t=RandomArray[poi,1000];                    (* here is a random array *)
