 Hi.
   sparse_matrix maybe don`t support comlex number very well,I can`t get the real or imag part of a complex number in the sparse_matrix, how to solve it?
  a simply example:
   

#include <boost/numeric/ublas/matrix_sparse.hpp>
#include <boost/numeric/ublas/io.hpp>
 
 
 int main () {
    using namespace boost::numeric::ublas;
      sparse_matrix<std::complex<double> > m (3, 3);
 
    for (unsigned i = 0; i < m.size1 (); ++ i) {
         for (unsigned j = 0; j < i; ++ j)
             m (i, j) = std::complex<double> (3 * i + j, 3 * i + j);
                         m (i, i) = std::complex<double> (4 * i, 0);
         }
     }
         std::cout <<(m(0,0)).real()<< std::endl;
 }
   
    Best!
