Question

In Hermitian matrix the diagonal elements are????

a... All Zero
b...All purely imaginary
c...All real
d... Either zero or purely imaginary

Answer 1

The entries on the main diagonal (top left to bottom right) of any Hermitian matrix are necessarily real, because they have to be equal to their complex conjugate. ... Hence, a matrix that has only real entries is Hermitian if and only if it is a symmetric matrix, i.e., if it is symmetric with respect to the main diagonal.
