Given a 4x4 non-Hermitian matrix, is there any method I can use to prove the eigenvalues are real, aside from actually computing them?
I'm looking for something like the converse of the statement "M is Hermitian implies M has real eigenvalues".
When can one say that the eigenvalues of a given matrix are real?
