calc_f.m (M) | Contains a system of equations that describes the steady-state operation of a heat exchanger network. |

calc_Jac.m (M) | Function to calculate the Jacobian matrix for a set of nonlinear algebraic equations. A simple central differencing scheme is used. |

ice_root.m (M) | Calculates the RGA (relative gain array) and DC (disturbance cost) for the 10.492 heat exchanger network. |

reduced_Newton.m (M) | Uses a reduced-Newton algorithm with a weak line search to solve a set of non-linear algebraic equations. |
