Eigenvectors for non-symmetric dense matrix (ScaLAPACK)

[zarkobodroski]

Hi,
Is there routine in ScaLAPACK for solving eigenvectors and eigenvalues for non-symmetric dense matrix?

Thanks.

Unfortunately no. There is no such things as an PDGEEV (the ScaLAPACK equivalent of LAPACK DGEEV). We have made some progresses recently thanks to contributions from Robert Granat, Bo Kågström, Meiyue Shao (Umeå University and HPC2N), and Daniel Kressner (École Polytechnique Fédérale de Lausanne). But we are yet missing the eigenvectors computation from the Schur form and a driver to link all the subroutines together. Cheers, Julien.

Dear Julien,

has there been any progress regarding the Schur decomposition?

best wishes
