Imaginary exponents with pure oscillation provide a “center” in the phase plane. The point (y, dy/dt) travels forever around an ellipse.

2.2.4.1 MATLAB Example: Phase Plot of a Pendulum We now enter the model of the pendulum into MATLAB much like we did for the previous examples. The simulation results are shown in Figures 2.20 and 2.21 for b = 0 and Figures 2.22 and 2.23 for b = 0.1. The basic m-file that runs th...
margin returns a warning if your system is not internally stable, that is, if your system is not closed-loop stable or contains pole-zero cancellations outside of the open left-half plane. example[Gm,Pm] = margin(sys,J1,...,JN) returns the gain margin Gm and phase margin Pm of the...
10.12 Linear Phase and Phase Unwrapping—MATLAB A DTFT X(ejω) is said to have linear phase if its phase is a line through the origin of the frequency plane. Let X(ejω)=2e−j4ω −π≤ω<π (a) Carefully plot the magnitude and the phase of X(ejω). Is the phase ...

how can i plot the arrows like in the targeted phase-plane portraits at the initial points?zeros is just used here to make the speed vectors of the same size of the position vectors.

I'm confused by the quiver and ode45 functions used to plot phase portraits. I want you use MATLAB to plot the isoclines and closed phase plane trajectories to model the predator-prey Lotka-Volterra system of equations: quiver(x1,x2,x1dot, x2dot) ...
