How do I plot a random number of rectangles using rectangle('Position', [x y w h])?

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

what is the value of b?

[Azzi Abdelmalek]

Unless b is very big, there is no problem in your code

Ok! I do not really know how to manipulate b in MATLAB so that it returns a random value and therefore a random amount of rectangles. Could someone help me with that?

[José-Luis]

How are you using it then? If you don't know how to manipulate b that is.

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