The order is the same. Eigenvector 1 is associated with eigenvalue 1,
eigenvector 2 is associated with eigenvalue 2,
(Note: the eigenvectors are orthogonal.) Cheers, Julien.

Hello,
I am currently using the zheev.f subroutine in order to determine the
eigenvalues and eigenvectors of a complex Hermitian matrix. I know the
eigenvalues appear in ascending order but I was wondering in what order the
eigenvectors appear in the output (i.e how to match them with their
respective eigenvalues).
Thanks
Emilie Guidez
