Additional facts related to Hermitian matrices include: • The sum of a square matrix and its conjugate transpose is Hermitian. • The difference of a square matrix and its conjugate transpose is skew-Hermitian (also called antihermitian). This implies that the commutator of two Hermitian matrices is skew-Hermitian. Witryna5 wrz 2015 · Inverse of the Cholesky factor of the p.d. Hermitian sym Toeplitz matrix T using Durbin recursions
WitrynaYou would only need a special algorithm for a matrix too large to handle by the usual methods. On the other hand, eigenvalues of large Toeplitz matrices can be numerically unstable, see e.g. Eigenvalues and Pseudo Eigenvalues of Toeplitz Matrices (Lothar Reichel, Lloyd N. Trefethen). WitrynaAbstract: A solution to the inverse eigenvalue problem for Hermitian Toeplitz matrices is presented. The approach taken is to first construct a real symmetric negacyclic …
WitrynaUsing the notion of displacement rank, we look for a unifying approach to representations of a matrix A as sums of products of matrices belonging to commutative matrix algebras. These representations are then considered in case A is the inverse of a Toeplitz or a Toeplitz plus Hankel matrix. Some well-known decomposition formulas …
