Dear all,

The following is a short example:
====================================================
#include <boost/numeric/ublas/matrix.hpp>
#include <boost/numeric/ublas/matrix_proxy.hpp>
#include <boost/range/adaptors.hpp>
#include <iostream>
int main() {
     boost::numeric::ublas::matrix<int> m(1, 2);

     std::cout << boost::size(column(m, 0)) << "\n";
     std::cout << boost::size(column(m, 0) | boost::adaptors::reversed) 
<< "\n";

     return 0;
}
====================================================
