eigenvectors calculated by LAPACK

Postby goldov » Sat Aug 05, 2017 3:26 am

Hi, i have a question realated to sgeev and dgeev subroutines used to calculate eigenvalues and eigenvectors of a dense and non-symmetric matrix, A*uj=lambda(j)*uj. in general, eigenvalues lambda(j) are complex and are not complex conjugate - in that case how to calculate the true eigenvectors u(:,j) using, for example, vr(:,k), where k=1...2n ? i would appreciate someones detailed answer. Thank you.
