title: How to define radius while drawing sphere in Matlab?
body: <p>I need to plot multiple sphere and I was using the example code from mathwork help as follows -     </p>
  
  <pre><code>figure
  [x,y,z] = sphere();
  surf(x,y,z)  % sphere centered at origin
  hold on
  surf(x+3,y-2,z)  % sphere centered at (3,-2,0)
  surf(x,y+1,z-3)  % sphere centered at (0,1,-3)
  daspect([1 1 1])
  </code></pre>
  
  <p>I need the spheres to be different radius. How can I define radius for each of these spheres? </p>
