making a matrice with conditions

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);

why do you use min()? I thought you would use max() because it can be max 20.

[John D'Errico]

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

ah thanks!
