MATLAB: How to plot a random number of rectangles using rectangle(‘Position’, [x y w h])

matlab rectangle

This is how I have tried. But it does not seem to work. As fast as I run the function, MATLAB gets in Busy-mode and never returns. What am I doing wrong?
function amount = draw_rectangle(b)
amount = b;
      for j =1:b;
          x = rand(1)*10;
          y = rand(1)*10;
          w = rand(1)*10;
          h = rand(1)*10;
          rectangle('Position', [x y w h])
          hold on;
      end
    end

Best Answer

close
hold on;
for k=1:randi(100);
       rectangle('Position', 10*rand(1,4))
end
hold off
