Given the symmetric tridiagonal matrix [2 1 01 0 1 2 use Givens rotations to find QR factorization and complete one iteration of the QR iteration. You may use matlab to do the matrix multiplications. Show all your steps and keep at least 4 significant digits in your calculations Given the symmetric tridiagonal matrix [2 1 01 0 1 2 use Givens rotations to find QR factorization and complete one iteration of the QR iteration.
