Hi everybody does anyone know how I can plot a quadrangle with four set points of (x,y) like : (0.4464,0.4234), (0.4180,0.4116), (0.4046,0.3774), (0.4289,0.3871) ? Thanks !

Your output is sometimes complex. You should fix this in your function, but you can also apply a quick fix here:
fplot(@(Lambda)abs(Steady_State(Lambda)))ylim([0 200])Ideally you should also make your function support vectorized inputs and deal with all the warnings (and suppress outputs by adding semicolons).
