The problem is that it only computes eigenvalues. I also want to
obtain the corresponding eigenvectors.

I am using

        GNU Octave, version 2.0.16 (i686-pc-linux-gnulibc1)

Looks much older than the version Dirk Laurie is using. Is the
version I am using too old?

Obsolete?

Does qz come with .16?

which is exactly what I want.

Do I have to upgrade to .30 or some thing?
