hypg_inv — hypergeometric quantile
[k]=hypg_inv(p,n,K,N)
p = a vector
n,K,N = parameters of the hypergeometric distribution (n = size of the population drawn, K = size of the class of interest among the whole population, N = size of the whole population).
k = The vectors of the smallest integers so that P(X <= k) >= p(i) for each coordinate i of p.
