Unformatted text preview: rows are zero in R, the last two columns of Q are not necessary and can be eliminated as in part c. However if the rank of A were to be 4, this would produce an nxn matrix R and all columns of Q would be necessary. (If the rank were to be three, the first three columns of Q would be used with the last row of R being zeros). 2. Used to check number 29 of section 5.2: A=[3 1; 4 7]; [Q,R]=qr(A) Q =0.6000 0.8000 0.8000 0.6000 R = 5 5 0 5Q verifies answer of U: u 1 =[3/5; 4/5] u 2 =[4/5; 3/5]...
