Hi,
is there a fix for the following compilation error ? It only happens
with gcc versions higher than 4.4. Thanks,
Nuno
~$ cat t1.cc #include <boost/numeric/ublas/matrix_sparse.hpp>
#include <boost/numeric/ublas/io.hpp>
int main () {
using namespace boost::numeric::ublas;
coordinate_matrix<double> m (3, 3, 3 * 3);
for (unsigned i = 0; i < m.size1 (); ++ i)
for (unsigned j = 0; j < m.size2 (); ++ j)
m (i, j) = 3 * i + j;
std::cout << m << std::endl;
}
