Hello,
I have a column variable with 20 random numbers between 0 and 19. How do I add +2 to all numbers but the numbers can be maximum 20?
Thanks in advance

You can use min()
x = randi([0 19], 1, 20);
y = min(x+2, 20);

You use min, because you want MATLAB to take the SMALLER of x+2 and 20. Ergo, min.
