Use MATLAB’S pplaneaml to draw the phase portrait of the system

Use MATLAB’S pplaneaml to draw the phase portrait of the system. Use -4 5 3:1 5 4 and —4 5 2:2 5 4. Generate enough trajectories to display the type of phase portrait clearly. Your result should look good enough to be accepted for a publication in a scienti?c journal. There is no partial credit for this part. so make sure it shines. 10 points (3) Use the discrete time analog Lin-+1 = F(x,-) of the dynamical system x' = Ax to plot dis- crete time trajectories in MATLAB. Your result should resemble the graph obtained using pplaneBm, otherwise there is no partial credit for this part. Use axis([-4 4 -4 4]) if necessary. 20 points
