Skew-hermitian matrix
Webb(c) This matrix is Hermitian. (d) This matrix is Hermitian, because all real symmetric matrices are Hermitian. One of the most important characteristics of Hermitian matrices is that their eigenvalues are real. This is formally stated in the next theorem. Proof Let be an eigenvalue of A and be its corresponding eigenvector. Webb24 mars 2024 · Antihermitian matrices are often called "skew Hermitian matrices" by mathematicians.

Stable Decomposition of Skew-Hermitian Matrices. If A is skew-Hermitian (AT = -A), Aasen's algorithm gives A=P2L2-P„L„TL„Pn-L2P2, where the Pj and L, are as above, Lj — Lj, but T is now skew-Hermitian. Since the diagonal of A is not necessarily null, element growth is bounded by 4"~2. However, when A is skew-Hermitian, we cannot use ...
