WitrynaA Hermitian matrix is a matrix that is equal to its conjugate transpose. Mathematically, a Hermitian matrix is defined as. A square matrix A = [a ij] n × n such that A* = A, where A* is the conjugate transpose of A; that is, if for every a ij ∊ A, a i j ― = a i j. (1≤ i, j ≤ n), then A is called a Hermitian Matrix.
