Problem with waitforbuttonpress and if command

Hi! I'm doing a matlab programs and I have a litle problem.

I want to open a number in a random form, but at the same time I want that matlab evaluate if exist an input from the keyboard. So, if I press a key, matlab reboot the loop 'for', but if I don´t press any key, matlab open the number, and so on.

For this reason, I'm using the comand 'if', but I have so many problems to advance it. I had used the 'switch' comand, but it give the same problem.

If anyone can help me.

My code is the next:

n=6; %number of repetitions of mi loop

for i = 1:n;

% Here, I want to have the 2 options, one that allows me to reboot the loop if i press any key, and another that give me a random number when no-press any key

   if senal = waitforbuttonpress || getkey       
   continue    %With this, the loop reboot

    else
   i=randperm(3,1);  %It give a random number
   disp(i)
   pause(1)

   end 
end

Thanks for all!

Button? Or keyboard key? getkey() is keyboard.

Keyboard input with wait is at http://www.mathworks.com/matlabcentral/fileexchange/8297
