Random numbers from the hypergeometric distribution
X = rhypg(num,n,K,N)
positive integer or a 2-vector [lig, col] of positive integers
nonnegative integers such that n<= N, K<= N
is the total number of elements of the population
is the number of elements which are randomly extracted K is the number of elements of the population which have the studied property
num-vector or a num-matrix of random numbers chosen from the hypergeometric distribution with parameters n,K,N
Random numbers from the hypergeometric distribution (inversion method).
