(Solved) : Part B B Col Display Message System Inconsistent Look Least Squares Solution Find Least Sq Q33300031 . . . .

Part (b): **If b∉Col A, display a message “The system isinconsistent – look for the least-squares solution” and, then, findthe least-squares solution in two ways: see (1) and (2) below. (1)Find the unique least-squares solution x3 by solving the normalequations T T AA A x b = and estimate the least-squares error ofthe approximation: n1 = norm(b x − ∗ A 3). Present the output inthe form of two messages: “The solution of the normal equations isx3” (output x3); and “The least-squares error of the approximationis n1= (output n1)”. (2) Find an orthonormal basis U for Col A.First, check if
