MATLAB: Loop / Repeat if random number = 0

if statementlooprandom number generatorzeros

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
