The inverse of a Hermitian matrix is Hermitian as well. Conjugate of a Hermitian matrix is also Hermitian. If A is Hermitian, then A*A and AA* is also Hermitian. Any square matrix can be represented as A + iB, where A and B are Hermitian matrices. In mathematics, the complex conjugate of a complex number is the number with an equal real part and an imaginary part equal in magnitude but opposite in sign. That is, (if and are real, then) the complex conjugate of is equal to The complex conjugate of is often denoted as or .
