WitrynaThe property of two matrices commuting is not transitive: A matrix may commute with both and , and still and do not commute with each other. As an example, the identity matrix commutes with all matrices, which between them do not all commute. If the set of matrices considered is restricted to Hermitian matrices without multiple eigenvalues ... WitrynaA skew-Hermitian matrix is the anti of a Hermitian matrix which is why the skew-Hermitian matrix is also known as the anti-Hermitian matrix. The skew-Hermitian matrix is closely similar to that of a skew-symmetric matrix. A skew-symmetric matrix is equal to the negative of its transpose; similarly, a skew-Hermitian matrix is equal to …
