nonsymmetric eigenvalue problem using SCALAPACK

Hi all,

I wanted to get the eigenvalues AND eigenvectors of a non-symmetric matrix using SCALAPACK. By using PxGEHRD and PxLAHQR I can get to the Schur form and get the eigenvalues, but I need the eigenvectors, left and right, as well. I don't know where to go next! I understand that in LAPACK I would use xTREVC or xHSEIN/xORMHR to get them. Is there a way using ScaLAPACK?

Thanks a lot.
A
