incidentally we're looking at ScaLAPACK's non-symmetric eigensolvers
right now. It's hard to say when it's going to be completed.
As it stands right now, you can only compute eigenvalues of
an upper Hessenberg matrix.

Hello, I'm a graduate student at Seoul Nat'l Univ. in Korea,
I have to solve eigenvalue problem for dense, nonsymmetric,
I looked for an appropriate routine offered in ScaLAPACK,
and found a PZGEHRD, PZLAHQR.
There are documents about NEP at slug(i.e ScaLAPACK User Guide).
0000000 They describe how to compute eigenvalues and eigenvectors in
the case of NEP.
To use PZLAHQR, howerver, I must input matrix Z from PZHSEQR.
But I can't find such routine any where.
1) Where can I find the PZGEEV routine... or when is it supposed to
2) Instead of using PZGEEV, how can use PZLAHQR without PZHSEQR..??
3) Would you show me the sample code(written in C) for NEP??
Thank you very much.
