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?</DIV> <DIV><BR /></DIV> <DIV>Thanks a lot.</DIV> <DIV>A</DIV> <DIV><BR /></DIV> Wed, 21 Oct 2009 16:45:31 GMT amolins 2009-10-21T16:45:31Z https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/nonsymmetric-eigenvalue-problem-using-SCALAPACK/m-p/906234#M11731 Hi all, <DIV><SPAN style="font-family: Verdana, Arial, Helvetica, sans-serif;"><BR /></SPAN></DIV> <DIV>I wanted to get the eigenvalues AND eigenvectors of a non-symmetric matrix using SCALAPACK.
