How do I create a column vector of random numbers between -40 and 40, with "n" entries?

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?

how to create a column vector named srcBits containing 20,000 randomly-generated bits.

@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)
