I know rand returns random values between 0 and 1 and randi returns random integers, but how do I create a column vector with random numbers within a certain range?

@Amit A, start your own question in a new thread, and there say how many elements you want in the vector and how many bits are in each number/element of the vector.

If you want random floating-point numbers:
n = 1000; % Pick A Number
rv = 80*rand(n,1)-40; % Vector Of Random Floating-Point Numbers
figure(1)
hist(rv,50) % Check Result (Optional)
