Properties of the Trace and Matrix Derivatives
... λ̄xT x = (Ax)T x = xT AT x = xT Ax = λxT x. Thus, all the eigenvalues are real. Now, we suppose we have at least one eigenvector v 6= 0 of A. Consider a space W of vectors orthogonal to v. We then have that, for w ∈ W , (Aw)T v = wT AT v = wT Av = λwT v = 0. Thus, we have a set of vectors W that, wh ...
