WebSep 25, 2024 · It is a real matrix with complex eigenvalues and eigenvectors. Property 3. Symmetric matrices are always diagonalizable. (The spectral theorem). This is also related to the other two properties of symmetric matrices. The name of this theorem might be confusing. In fact, the set of all the eigenvalues of a matrix is called a spectrum. Webmatrix and is assumed to be Hermitian i.e. it is the conjugate transpose of itself (2). Aand⃗bare known, while ⃗xis the unknown vector whose solution we desire. Dimensions of ⃗xand bare M×1. If Ais not Hermitian then it can be converted into a Hermitian matrix A′as shown in (3), then the resulting system of equations is shown in (4,5,6 ...
