% Two dimensional ordered filtering.
%
% Ordered filter replaces an element of @var{A} with the @var{nth} 
% element of the sorted set of neighbours defined by the logical 
% (boolean) matrix @var{domain}.
% Neighbour elements are selected to the sort if the corresponding 
% element in the @var{domain} matrix is true.
% 
% The optional variable @var{S} is a matrix of size(@var{domain}). 
% Values of @var{S} corresponding to nonzero values of domain are 
% added to values obtained from @var{A} when doing the sorting.
%
% Optional variable @var{padding} determines how the matrix @var{A} 
% is padded from the edges. See @code{padarray} for details.
