How to draw the collision of two ball with Matlab?

How to draw the collision of two ball with Matlab? I know the governing equations of the velecitys of two balls, but it seems hard to carry out.

I think using these built-in functions will help:

1. handle01 = plot([X1,X2],[Y1,Y2],'.','MarkerSize',10);% draw two points to represent two balls.

2. handle01.XData = [newX1,newX2];handle02.YData = [newY1,newY2];drawnow;% update the location

and you could plot the collision more beautiful with a little more input arguments according the matlab manual.

here is a pseudo-code:

handle01 = plot([x1,x2],[y1,y2],'.','MarkerSize',10);
for ind1 = 1:maxIteration
    [x1,y1,x2,y2] = yourGoverningEquation(...);% update the location after deltaT time
    handle01.XData = [x1,x2];
    handle02.YData = [y1,y2];
    drawnow;
end

The attach file (Elastic collision -Wikipedia.pdf) is the theory of collision.
