## 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}.
