Asking for linux-library

Hi everyone,

I'm working with complex non-symmetric matrices and I want to get the
eigenvalues/eigenvectors of them, i.e., the eigenvalue problem for
unitary matrices.

Does anyone know about a Fortran 90 subroutine (library) that can perform this job?

I checked on LAPACK but haven't found one.

For more complete information about compiler optimizations, see our Optimization Notice.

Look at the section "Nonsymmetric Eigenvalue Problems" in the MKL reference manual. There is a "decision tree" diagram there to help you pick the appropriate routine(s) for your purposes.

Just for reference, after working with the decision tree, I found a better option and it is the subroutine zgeev implicit in lapack;
apparently, it has all the subroutines describe in the decision tree you just called.

Check netlib too, I think there's a eigen problem library but I can't remember its name.
