I would like some help in writing a program for a flight simulation. I have to enter a control matrix and from this I must obtain graphs with a function of time. However, I am stuck with finding the equilibrium state. I must use the Newton-Raphson method on the first order differential state space equation form. ie x'=Ax+Bc where x is state variables c is the control matrix to gain the trimmed state varibles in other words I have to obtain the controls and states for equilibrium steady level flight
