How to add parameters to randi inputs

I need to use randi to produce a string of random numbers, the string should either end when the last digit of the last number is 9 or the the output reaches 15 numbers. Also the numbers can only be between 1 and 999. I know how to use the randi function however I don't know how to use it with all of these parameters.

v = randi(999,15,1);
for k = 1:15
  if mod(v(k),10) == 9
    v = v(1:k);
    break;
  end
end
% Vector v is the desired result
