Question: Use the factorization A = QR to find the least-squares solution of Ax = b. 4 = 3 3 3 3 500S = 1/2 1/27

Use the factorization A = QR to find the least-squares solution of Ax = b.


4 = 3 3 3 3 500S = 1/2 1/27 - 1/2

4 = 3 3 3 3 500S = 1/2 1/27 - 1/2 1/2 - 1/2 1/2 1/2 1/2_ 6 0 55 . b = 9 -8 5 -3
