MATLAB: How to create x number of circles and then animate them

animatecircleforgraphloopMATLABplot

I want to let the user specify how many circles there are to be plotted, each circle having a different size and all of them are in the center of the plot. Then I want to animate them so each circle gets a random speed to a random direction in the 2D plot. Is this possible?
I made this function to generate n numbers of random triangles but I don't know how to animate them with a certain speed and direction.
 function circles(n)
   for i = 1:n
    size = randi(100);
    pos = -size/2;
    rectangle('Position',[pos pos size size],'Curvature',[1 1]);
    end

Best Answer

function circles(c)
rectangle('Position',[-250 -250  500 500]);
size =randi([1,100],1,c); 
k=-size/2 ;
l=-size/2 ;
m=-10+20*rand(1,c);
n=-10+20*rand(1,c);
for i=1:20
  for a =1:c
  r(a)=rectangle('Position',[k(a) l(a)  size(a) size(a)],'Curvature',[1 1]);
    k(a)=k(a)+m(a);
    l(a)=l(a)+n(a);
    end
refreshdata;
pause(.1);
if i==20
    continue
end
delete(r(1,:))  
end
After hours of dedicated work , I just wrote it as a beginner Matlaber. This would do it .Cheers ;
