[Trilinos-Users] trillinos diagonalization

Dear Trilinos developers and users,

I'm using Anasazi package to diagonalize sparse matrices with Epetra_CrsMatrix.
i gave same vectors as an initial eigenvectorw(so it is not orthogonal)

and the time and iteration number of first step of diagnoalization were different between each trial with same input.

however eigenvalues were almost same in tolerance value.

and other steps didn't show this phenomena

i guess that the program randomized the initial eigenvectors even i set some initial eigenvectors.

is there any reason of this phenomena?

Best regards,

jaechang lim
