If your task is that simple, I prefer updating the XData and YData rather than using the animatedline method. This is faster and more efficient. Instead of deleting and drawing a new point on each iteration, it merely changes the coordinate value of the point that is already drawn. If this is too fast, you can control the approximate timing by using pause() within the loop to slow it down.
Here's an example (just run this to watch a dot move along a sinusoidal trajectory).
x= 0:0.1:2*pi;
y= sin(x);
figure
ph = plot(x(1), y(1), 'r*'); %plot initial point
set(gca,'Xlim',[0 6.5], 'Ylim',[-1 1])
for i=1:length(y)
ph.XData = x(i); %change x coordinate of the point
ph.YData = y(i); %change y coordinate of the point
drawnow
pause(0.05) %control speed, if desired
end
If you prefer to use the animatedline method, just insert clearpoints() before you call addpoints().
for i= 1:length(Ball)
clearpoints(curve)
addpoints(curve,x(i),y(i));
drawnow
end
