trying to make a random number sequence similar to an MLS sequence

I'm trying to create a random number sequence like this one: -

x = 2*rand(N,1)-1; % generate input noise signal

except instead of the numbers being at all different values between -1 and 1, I'd like them to be either -1 or 1 only.

Does anyone know how I might do this?

This is nothing like an MLS sequence. What you are looking for is often called Bernoulli noise.

a = 2*(randi(2,N,1)-1.5)

a = 2*(rand(N,1)>0.5)-1
