2/ eigenvects(exact(a)) or jordan(exact(a)) returns simple answers, and you can of course replace in this answer an eigenvector by the conjugate eigenvector of the conjugate eigenvalue.

These are better. I never knew that it was convention to normalize the last row of a the eigenvector matrix to 1 if the results were approximate. Maybe, I'll write a small routine to take care of that.
