Consider the process flow diagram shown in Fig. 2.14. We can write this out as the system of equations

The first four equations are the mass balances; the next eight equations are the process specifications.

(a) Write a MATLAB program that generates the matrix A and vector b required to solve the problem for this set of equations.

(b) Write a MATLAB program that solves this system using naive Gauss elimination. What happens? How do you fix it?
