title: Drawing rectangles with different angles with Psychtoolbox Matlab
body: <p>I'm drawing 4 rectangles with randomized rotations. They seem randomized in terms of their angels, however I need them to be a little bit different. The rectangles should not be close to each other, they all should be at least 10 degrees apart. And this also should be randomized. How can I define this? Thank you!</p>
  
  <pre><code>rot_angle1=randi(360); 
  rot_angle2=randi(360); 
  rot_angle3=randi(360); 
  rot_angle4=randi(360); 
  rect_array=255*ones(1,1);
  t1=Screen('MakeTexture',w,rect_array);
  t2=Screen('MakeTexture',w,rect_array);
  t3=Screen('MakeTexture',w,rect_array);
  t4=Screen('MakeTexture',w,rect_array);
  t5=Screen('MakeTexture',w,rect_array);
  
  destrect(1,:) = (ul_c + stim_array);
  destrect(2,:) = (ur_c + stim_array);
  destrect(3,:) = (ll_c + stim_array);
  destrect(4,:) = (lr_c + stim_array);
  
  Screen('DrawTexture',w,t2,[],destrect(1,:),rot_angle1);
  Screen('DrawTexture',w,t3,[],destrect(2,:),rot_angle2);
  Screen('DrawTexture',w,t4,[],destrect(3,:),rot_angle3);
  Screen('DrawTexture',w,t5,[],destrect(4,:),rot_angle4);
  Screen('Flip',w);
