I want to know how to perform animation of a moving figure using matlab. I know to perform animation of points movement in a plot but I need to know to animate the figure which moves based on center point of a figure. For example I provide some moving commands to center of circle, based on movement of that point the circle should be able to move. Is it possible using matlab. Please let me know. Thank you.

c = [0 0] ; % center of circle
th = linspace(0,2*pi) ;
r = 0.1;
x = c(1)+r*cos(th) ;
y = c(1)+r*sin(th) ;
h = plot(x,y,'r') ;
axis equal
%%animation
for i = 1:100
c = rand(1,2) ; % center of circle
x = c(1)+r*cos(th) ;
y = c(1)+r*sin(th) ;
set(h,'XData',x,'YData',y) ;
axis([-2 2 -2 2])
drawnow
end

Hello KSSV, you have misunderstood me. I am just referring circle as example. I just want to know if is possible move entire figure based on the movement of a fixed point. Thank you.
