Re: returning a ublas matrix from a function

Thank you. I am just a beginner, i am more used to matlab due to which i get
confused quite quickly. However i slowly came over the problem. but i now
face a new problem if possible for you can explain with a little patience it
would be of great help.


#include <boost/numeric/ublas/matrix.hpp>
#include <boost/numeric/ublas/io.hpp>

using namespace boost;
using namespace boost::numeric::ublas;


typedef boost::numeric::ublas::matrix<double> BMT;

BMT fun(int w,int h)
  {

    BMT M[3]=
          {
        boost::numeric::ublas::scalar_matrix<double>(w, h),
        boost::numeric::ublas::scalar_matrix<double>(w, h),
        boost::numeric::ublas::scalar_matrix<double>(w, h)
    };

  return M[2];
  }

int main()
{

    unsigned w,h;
    w = 2;
    h = 2;
    boost::numeric::ublas::scalar_matrix<double> Z[3];
    Z[3]=fun(w,h);

    std::cout<<fun&lt;&lt;std::endl;
    return 0;
}

and I end up with error: no match for 'operator=' (operand types are
'boost::numeric::ublas::scalar_matrix&lt;double>' and 'BMT {aka
boost::numeric::ublas::matrix<double>}')
     Z[3]=fun(w,h);
         ^

is my approach correct or have I misunderstood something?
thanks in advance
