[Trilinos-Users] EIGENVECTORS OF A LARGE SPARSE NON-HERMITIAN MATRIX

I want to get the largest eigenvalue and corresponding eigenvector of a
real large sparse non-symmetric matrix.
I modified the Anasazi BlockKrylovSchurEx example, building my own matrix.
The example does give the eigenvalues but I cant get it to give the
Teuchos::RCP<MV> evecs = sol.Evecs;
std::vector<int> index = sol.index;
and cout << "Eigenvectors" << evecs <<endl;
would be enough, but I am clearly missing something here.
Would you have an idea how to get it to output the eigenvectors? (or at
least the one associated with the largest eigenvalue)
Thanks in advance!
