The diagonal elements of a Hermitian matrix are allreal

1.	The diagonal elements of a Hermitian matrix are allreal
Answer» Answer: Only the MAIN diagonal ENTRIES are NECESSARILY real; Hermitian matrices can have arbitrary COMPLEX-valued entries in their off-diagonal elements, as long as diagonally-opposite entries are complex CONJUGATES. A matrix that has only real entries is Hermitian if and only if it is symmetric. mark me as a BRAINLIST.
