% Return an @var{r} by @var{c} matrix of random samples from the Pascal
% (negative binomial) distribution with parameters @var{n} and @var{p}.
% Both @var{n} and @var{p} must be scalar or of size @var{r} by @var{c}.
%
% If @var{r} and @var{c} are omitted, the size of the result matrix is
% the common size of @var{n} and @var{p}. Or if @var{sz} is a vector,
% create a matrix of size @var{sz}.
