Actually theoretically matrix is hermitian if conjugate of A transpose is A itself. Spectral properties. In physics the dagger symbol is often used instead of the star: Rarely heard "complex transpose" or "hermitian transpose". Complex eigenvalues for hermitian matrix. ˈ l ɛ s. k i /) is a decomposition of a Hermitian, positive-definite matrix into the product of a lower triangular matrix and its conjugate transpose, which is useful for efficient numerical solutions, e.g., Monte Carlo simulations.It was discovered by André-Louis Cholesky for real matrices. I have a complex Hermitian matrix, say W, which is obtained by solving a convex optimization problem.In order for this matrix to be the result of my original problem, W must satisfy the following condition rank (W) = 1.When I checked this condition, MATLAB gives me an answer 3 for 3x3 W matrix. ...
