Create a column vector of length "num" that consists of random numbers that are uniformly distributed between 2 and 9. (D)
D = randi([2 9],num,1);
D = 2+ 7.*rand(num,1) ;
Why aren't those two true? And what would be the right one?

You need to apply the floor() function to rand to get integer results, and your range multiplier isn't quite correct for the range you want. E.g.,
D = 2 + floor(8.*rand(num,1)); % <-- Changed 7 to 8 and added floor() function
