[petsc-users] routines called in LAPACK interface of SLEPc

[Umut Tabak]

Dear SLEPc team,

May I kindly ask which LAPACK routines are called in the LAPACK 
interface of SLEPc?

And what kind of checks do you conduct to check if the matrix is 
symmetric or not?

I have some matrices which are not completely symmetric however the 
off-diagonal terms are really small(orders: 1e-16) and I used Intel MKL 
Lapack routines for my problems.

But, I could not get the correct eigenvectors, however I can get the 
correct eigenvalues on which I am puzzling with.

Best regards,
Umut
