% @deftypefn {Function File} {} hygecdf (@var{x}, @var{t}, @var{m}, @var{n})
% Compute the cumulative distribution function (CDF) at @var{x} of the
% hypergeometric distribution with parameters @var{t}, @var{m}, and
% @var{n}. This is the probability of obtaining not more than @var{x}
% marked items when randomly drawing a sample of size @var{n} without
% replacement from a population of total size @var{t} containing
% @var{m} marked items.
%
% The parameters @var{t}, @var{m}, and @var{n} must positive integers
% with @var{m} and @var{n} not greater than @var{t}.
