The SOR method of iteration has an iteration matrix G given by where w is a real number, L is strictly lower-triangular, and U is strictly upper-triangular, and D is a diagonal matrix. Show that if 0 < w 〈 2, then SOR converges, and it diverges otherwise. (Hint: Use the fact that the determinant of a matrix is the product of its eigenvalues, and det(AB) = det(A)det(B).)

In this exercise, you will work with a QR factorization of an mxn matrix. We will proceed in the way that is chosen by MATLAB, which is different from the textbook presentation. An mxn matrix A can be presented as a product of a unitary (or orthogonal) mxm matrix Q and an upper-triangular m × n matrix R, that is, A = Q * R . Theory: a square mxm matrix Q is called unitary (or orthogona) if -,or equivalently,...
