Hello all,
why the codes below is wrong in g++ 3.4.2?
an error occurs in the line: cout<<CMatrix<double>::eye(5);
--------------------------------------
#include <ostream>
#include <boost/numeric/ublas/matrix.hpp>
#include <boost/numeric/ublas/io.hpp>
using namespace boost::numeric::ublas;
using namespace std;
template <class T>
class CMatrix
{
matrix<T>mat_;
public:
CMatrix(const identity_matrix<T>& m) { mat_ = m; }
static CMatrix<T> eye(int size) { return identity_matrix<T>(size); }
template <class T_>
friend ostream& operator << (ostream& os, CMatrix<T_>& m);
};
template<class T_>
ostream& operator << (ostream& os, CMatrix<T_>& m)
{
os<<m.mat_;
return os;
}
int main()
{
CMatrix<double>I = CMatrix<double>::eye(5);
cout<<I;
cout<<CMatrix<double>::eye(5);//this line ==> error
}
----------------------------------------
Thanks in advance!
