What kind of probability distribution do you wish these numbers to have over this interval? If it is to be uniform use 'rand' with appropriate scaling and offset.

You never looked up rand() in the help did you? Otherwise you would have noticed Example 1 which solves your problem
Example 1
Generate values from the uniform distribution on the interval [a,b]:
r = a + (b-a).*rand(100,1);
and I'm pretty sure you would have figured out a is 2.2 and b is 22 and you wouldn't have needed to wait for Simon to do it for you. Please mark the answer as Accepted.
