[petsc-users] How to get the eigenvectors in Slepc

Sorry and thank you for clarifying that,
One last question, I got the correct eigenvalues, now I got the 
eigenvectors, but they differ from the exact solution. 

For example, for the first eigenvalue(2405.247) I got the following eigenvector 
set where it differ from the exact solution, what could be the possible reason of that?

Regards,
