statistics: y = hygepdf (x, t, m, n)
statistics: y = hygepdf (…, "vectorexpand")

Hypergeometric probability density function (PDF).

For each element of x, compute the probability density function (PDF) at x of the hypergeometric distribution with parameters t, m, and n. The size of y is the common size of the input parameters. A scalar input functions as a constant matrix of the same size as the other inputs.

This is the probability of obtaining x marked items when randomly drawing a sample of size n without replacement from a population of total size t containing m marked items. The parameters t, m, and n must be positive integers with m and n not greater than t.

If the optional parameter vectorexpand is provided, x may be an array with size different from parameters t, m, and n (which must still be of a common size or scalar). Each element of x will be evaluated against each set of parameters t, m, and n in columnwise order. The output y will be an array of size r x s, where r = numel (t), and s = numel (x).
