MATLAB offers several plotting routines. The "quiver" function may be ideal to plot phase-plane portraits. I found an interesting link that has some code and discussion on this topic. You can start here and build up:

There are also app solutions for this problem. For example pplane, which I used in undergrad (almost 10 years ago now). We also created a new app for analyzing the phase plane, you can find it here.

xdot = -y, ydot = -x sketch the vector field.
