Just something that came to attention :

In the comments of dgeev & dgeevx functions

*  The left eigenvector u(j) of A satisfies
*                u(j)**T * A = lambda(j) * u(j)**T
*  where u(j)**T denotes the transpose of u(j).

u is supposed to satisfy u(j)**H * A = lambda(j) * u(j)**H

just for the ppl using it not to be confused when it comes to result
verification ( || u(j)**T * A - lambda(j) * u(j)**T || is large in case
of complex eigenvalue )
