May 12, 2017 at 11:25 comment added Joël Ouaknine "Reasonably nice" is anything that will make the assertion true... :) $M$ is not necessarily symmetric (otherwise, as pointed out by Anthony Quas above, the spectrum would be entirely real).

May 12, 2017 at 0:36 comment added Anthony Quas If the matrix were symmetric, I wouldn't expect complex conjugate eigenvalues.
May 12, 2017 at 0:18 comment added Henry.L Is $M$ symmetric ? What do you mean by "reasonably nice"?
