## @deftypefn {Function File} {} pascal_inv (@var{x}, @var{n}, @var{p})
## For each element of @var{x}, compute the quantile at @var{x} of the
## Pascal (negative binomial) distribution with parameters @var{n} and
## @var{p}.
##
## The number of failures in a Bernoulli experiment with success
## probability @var{p} before the @var{n}-th success follows this
## distribution.
