An important result of linear algebra, called the spectral theorem, or symmetric eigenvalue decomposition (SED) theorem, states that for any … Web(1) Any real matrix with real eigenvalues is symmetric. False. The matrix 1 1 0 2 has real eigenvalues 1 and 2, but it is not symmetric. (2) A symmetric matrix is always square. True. If Ais symmetric, then A= AT. If Ais an m nmatrix, then its transpose is an n m matrix, so if these are equal, we must have m= n. (3) Any real matrix with real ...
