% @deftypefn {Function File} {} median (@var{x}, @var{dim})
% If @var{x} is a vector, compute the median value of the elements of
% @var{x}. If the elements of @var{x} are sorted, the median is defined
% as
% @tex
% $$
% {\rm median} (x) =
% \cases{x(\lceil N/2\rceil), & $N$ odd;\cr
% (x(N/2)+x(N/2+1))/2, & $N$ even.}
% $$
% @end tex
% @ifnottex
%
% @example
% @group
% x(ceil(N/2)), N odd
% median(x) =
% (x(N/2) + x((N/2)+1))/2, N even
% @end group
% @end example
% @end ifnottex
% If @var{x} is a matrix, compute the median value for each
% column and return them in a row vector. If the optional @var{dim}
% argument is given, operate along this dimension.
