You should not need to perform any MATLAB coding to answer these following questions. You certainly can, though, to check your answers if needed. You may answer these questions as comments in your m-file. Consider the following inverse matrix entered into MATLAB, which can be used to solve a problem of the form Ax = b using the solution form: x = A-lb. Ainy = [0.10 0.02; 0.04 0.12]; (a) If I increase the first element b of the input vector by 2 units, by how much will the second solution output X2 change? (b) By how much would I need to decrease the input b2 to cause a decrease of 0.6 units in X2
