% 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 impad for details.
