Part3: In this part of the code end points of the rod is set to zero temperature. Modify the Matlab code so that the initial temperature at the rod is 200 at the half length of the rod and 0 at the rest of the rod. Hand calculate the analytical solution for the temperature in this case. Plot analytical and numerical solutions. Do you expect to see the heat diffusing the way you see in the graph? Justify your answer by comparing this graph by comparing your analytical and numerical solutions.
