Aug 16, 2014 at 18:43 | comment | added | Yemon Choi | Unless I have misremembered, even if a square matrix $A$ is unitarily conjugate to a triangular matrix $D$, it might not be the case that $A+A^\top$ is unitarily conjugate to $D+D^\top$. Therefore I think that the question as stated really does want to start with the assumption that $D$ is triangular. | |
