Hermitian semidefinite matrix

WitrynaIn this paper, we first present a local Hermitian and skew-Hermitian splitting (LHSS) iteration method for solving a class of generalized saddle point problems. The new method converges to the solution under suitable restrictions on the preconditioning matrix. Then we give a modified LHSS (MLHSS) iteration method, and further extend … Witrynadeterminant of inverse of a symmetric (or Hermitian) positive definite matrix, $\det X^{-1}$, which is the same as the product of the inverses of the eigenvalues. When used inside a CVX specification, det_inv constrains the matrix to be symmetric (if real) or Hermitian (if complex) and positive semidefinite.
