Hello,
I have been getting compiling errors when using coordinate_matrix. For example:
#include <boost/numeric/bindings/ublas/matrix_sparse.hpp>
using namespace boost::numeric::ublas;
// File: b.cpp
int main ()
{
coordinate_matrix<double> A(5, 5, 12);
A(0, 0) = 2.;
A(0, 1) = 3;
A(1, 0) = 3.;
A(1, 2) = 4.;
A(1, 4) = 6;
A(2, 1) = -1.;
A(2, 2) = -3.;
A(2, 3) = 2.;
A(3, 2) = 1.;
A(4, 1) = 4.;
A(4, 2) = 2.;
A(4, 4) = 1.;
return 0;
}
The errors are:

If I change it to "compressed_matrix" it compiles just fine.
I just updated boost and bindings through svn.
Any ideas?
