Web12. A reasonable alternative, is to construct an explicitly Hermitian matrix by exploiting the fact that any matrix, M, can be written as the sum of a Hermitian matrix, H, and a skew-Hermitian (or anti-Hermitian, if your in physics) matrix, S. This implies that a matrix can be made Hermitian simply by. H = 1 2 ( M + M †) WebMar 18, 2024 · Examples Theorems2.1 allnonzero Theorem2.3. Example identitymatrix.
