Let A be an mxn matrix with a singular value decomposition A=UZV, where U is an mxm orthogonal matrix, Σ is an mxn "diagonal" matrix with r positive entries and no negative entries, and V is an orthogonal nxn matrix. Suppose A is square and invertible. Find a singular value decomposition of A-¹. -1 If f A is square, then man and so A, U, E, and V are all nxn matrices. If A is invertible as well, then rank A= and all of the diagonal entries of Σ are Which of these matrices are invertible? Select all that apply. A. U B. E C. V D. None of these Therefore, a singular value decomposition of A1 is A-1 =
