MATLAB
Determine an Ax = b problem to show that the condition number is
very critical in finding the unknown vector x with minimum error.
Use MATLAB in this problem. You may come up with such an A matrix
that would show the effect of condition number in solving Ax=b
problem. Compare different approaches we mentioned in solving Ax=b
problem. Comment on the solutions, errors and condition
numbers.

Problem 2. In this problem we consider the question of whether a small value of the residual kAz − bk means that z is a good approximation to the solution x of the linear system Ax = b. We showed in class that, kx − zk kxk ≤ kAkkA −1 k kAz − bk kbk . which implies that if the condition number kAkkA−1k of A is small, a small relative residual implies a small relative error in the solution....

4. The illustrative examples should show you that the simple fixed point iterations can be very slow, An alternative algorithm can be derived by using Newton's method. Suppose that A is symmetric and show that if A is equilibrated by D(x) thern Show that ef = D(x)A + D(Ax). and hence derive a Newton method for solving the symmetric equilibration problem and write a MATLAB function to carry it out.
