Implement the following simple version of QR iteration with shifts for computing the eigenvalues of a general real matrix A Repeat until convergence: 1. o an,n (use corner entry shift) C as 2. Compute QR factorization QR= A- oI 3. A RQ ol (These steps will be casy if you use a package such as MATLAB but more involved if library routine for the QR factorization or write your own.) What convergence test should you use? Test your program on...

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).)

1. (4) Find the QR decomposition of the matrix A = -1 0 2 1
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,...
