How do I code for placing an unknown number of Checkboxes?

Hi there

I'd like to have a simple GUI where a number of checkboxes are placed programmatically. This number depends on user input so may vary. Let's say that on day 1, M may contain ['A1','A2'] but on day 2, it may have ['A1','A2','A3']. How do I generate a code that will place a number of checkboxes dependent on the size of M?

Thanks very much for any help on this matter

matlab/java has no ability to create code like this, use Perl instead.

numChk = inputdlg('Number of Check Boxes');
numChk = str2double(numChk);
uh = zeros(1,numChk);
for i = 1:numChk
   uh(i) = uicontrol('Style','check');
   if i > 1
      pos = get(uh(i-1),'Position');
      pos(2) = pos(2)+20;
      set(uh(i),'Position',pos)
   end
end

This is good stuff Shaun. Exactly what I needed. Thanks a lot!
