Loop / Repeat if random number = 0

I have good and fun code and it is working very well.

However, I am getting an error when I get zero (0) from my "random integer generator":

n=round(200.*rand)

Is there any way I can tell the script to rerun the calculation for n, if n=zero? I am unable to change the variable n, and despite the low chance of getting two n=0 I want to "reroll" until n is definitely not equal to zero. Any idea how to do this?

Try

n = round(200*rand);
while (n == 0)
  n = round(200*rand);
end

Or, even better,

n = randi(200); % generates random integer between 1 and 200

n = 1+round(199*rand)
