Question

the matrix A is Hermetian​

Answer 1

Answer:

Skew-Hermitian Matrix

A square matrix, A , is skew-Hermitian if it is equal to the negation of its complex conjugate transpose, A = -A' . In terms of the matrix elements, this means that. a i , j = − a ¯ j , i . The entries on the diagonal of a skew-Hermitian matrix are always pure imaginary or zero.
