Saving an animation into an avi file

How can I save the animation that results from calling playTrajectory(10,pi/4) into an avi file... I know I have to use the movietoavi function but I'm not sure how I would do that.

function [x , y]= playTrajectory(Vo,O)

global g

g = 9.8 ; % m/s

for t = (0:0.05:1.5);

x = Vo * cos(O) * t ;

y = Vo*(sin(O)*t)-(0.5*g*(t.^2));

plot(x,y,'*')

axis([0,10.61,0,2.55]); xlabel('range') ylabel('height') pause (1) ; end

end
