Hi, I am trying to use MATLAB to create a model that can solve a set of equations. I have attached an image of the equations I am trying to solve. Essentially, there are 3 unknowns, Tout, Tp & Tg.
I wanted to ask which would be the best way to solve this on MATLAB, i have tried to use matrices but the temperatures I am getting are very high. Is there any other method that could be used to solve these equations?
Kind regards
