MATLAB command subplot

Figure 1.17 shows the MATLAB-generated figure that contains two subplots. The first subplot command picks the first row of this panel and plots the cosine function in it. The second picks the second row and plots the sine function in it. In this way, the two subplots are vertically aligned. 

Exercise your command of MATLAB by trying to replicate the three graphs in Figure 3.15. Learn about the subplot, xlabel, ylabel, and title MATLAB commands and how to use them. 

In threeCSTR.m, please note the use of the subplot MATLAB command that draws six separate graphs in our code, namely two for each tank.
