What is the answer to this question with the outcome of my code on matlab?

Converting A to upper triangular: A (18 , 37) = -3. 676271e+00 b ( 39) - 5. 227440e-01 gauss answers x (8) = x (46) = x (53) = x ( 70) = res norm = 3. 1086e-15 Matlab answers * (8 ) -6. 981887e-04 x ( 46) -2. 847151e-04 x (53 ) - -4. 7934950-04 x (70) = 2. 269370e-04 quiz norm = 5. 9068e+05 Quiz norm Published with MATLABR R2025aSay you computed the solution vector to the given system in question 1 (Same matrix [A] and vector {B}) of linear equations as a vector of all 1's as below {ac} = . 80 x 1 What would the Infinity norm, L., of the residual vector be using this solution vector? O Loo = 1.000 O Loo = 3.1086E-15 O There is no way to determine the residual vector given the solution vector. O Loo = 7.477 O L. = 74770 OLD = 7477
