Suppose A is a symmetric n x n matrix with n positive eigenvalues. Explain why an orthogonal diagonalization A = PDPT of A is also a singular value decomposition of A, with U = P =V and E = D. [Hint: First, explain why this is equivalent to showing the singular values of A are exactly the eigenvalues of A. Then show this is the case with these assumptions on A.]
