Section 15
% Here you may write any functions of your own, that you want to call from
% the interaction function, but never need to call from outside it.
% Remember that they do not have access to any variables except those
% that you pass as parameters, and cannot change anything except by
% returning new values as results.
% Whichever section they are called from, they must respect the same
% restrictions on what modifications they are allowed to make to the mesh.

% For example:

Section 16
% function m = do_something( m )
%   % Change m in some way.
% end

% Call it from the main body of the interaction function like this:
%       m = do_something( m );
