@Tom, Gerald: I apologize for being unclear. I've now corrected my question (I haven't done that before since I thought editing already posted questions could also be confusing). |

To clarify the situation - if a real symmetric matrix has one real eigenvalue, all its eigenvalues are real (which can be proved by induction)! |
