I show the particle positions with plot(x,y,'*') . Now i am curious how could I plot the velocities as arrows starting from the particles. One method came into my mind is to use arrow.m from our file exchange center and plot arrows after calculating the end of the arrow with vx and vy. I am still thinking whether do we have any other choices? with quiver? <br> <br> Any suggestions and comments are welcome. Thank you in advance. <br> <br> Jayson
