% Gives as output a specified submesh, and the lists of nodes and element that are mantained.

% Input:
% @itemize @minus
% @item @var{imesh}: standard PDEtool-like mesh, with field 'p', 'e', 't'.
% @item @var{intrfc}: row vector containing the number of the internal
% interface sides (numbering referred to mesh.e(10,:)) that should be
% mantained. Could be empty.
% @item @var{sdl} (subdomain list): row vector containing the list of the subdomain that are going to be extracted.
