Assuming your matrix is dense, the answer is "RTFM".
If you do
man -k eigenvector
on the Cray you will get a list of routines. The one you
probably want is either SGEEV (for REAL) or CGEEV (for COMPLEX).
These routines are from the LAPACK package, which you can
get from Netlib for almost any existing machine. Cray has done
you the favor of installing it for you.
