Hermitian Matrix: Definition, Formula, Properties & Examples

WebA Hermitian matrix can be expressed as the sum of a real symmetric matrix plus an imaginary skew-symmetric matrix. The addition (or subtraction) of two Hermitian matrices is equal to another Hermitian matrix, since: The result of the product of a Hermitian matrix and a scalar results in another Hermitian matrix if the scalar is a real number.

WebA 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.

WebThe sum or difference of any two Hermitian matrices is Hermitian. Actually, a linear combination of finite number of self-adjoint matrices is a Hermitian matrix. The inverse of an invertible Hermitian matrix is Hermitian as well.
