Re: Matrix with vector interface.

The easisest way, which dos not require a poxy would be to use 
boost.range and implement a suitable

begin(m) and end(m) along with the required iterator and typedefs.

than your example would look like:

main()
{
       matrix m;
       std::sort(begin(m), end(m), less_module);
}
