Oct 24, 2016 · It computes just about everything that you could possibly want to know about the trajectory for a single angle. Create Stream Particle Animations Yes you're right, the reason for this is the time it takes to redraw the whole plot, matlab just isn't fast enough, so this "eats into" the time. If you put slower velocities you'll see it really does get slower. Once the loop is complete, plot the position over time. e. The simplest way is to do multiple initial particle postions is just to make a loop around the ode solver feeding it new initial conditions.
