A is 4X2 matrix that is not shown here. B is the following matrix 26 37 48 59 The Q-factor in the QR-factorization of A is the same like the Q-factor in the QR-factorization of B (But the R-factors are not the same, otherwise A=B !). Let W be the range of A, and let b-[13 10 10 10]. Let w* be the least square approximation from W to b. Fill in the blank w*(1) (like in 2.34 or 0.76) Hint: There is not enough information in the question to solve Ax=b least squares. But there is enough information in order to find W.
