We analyze the underlying uniform PRNG of this function, based on the matlab code By default, the random number generator (rng) in MATLAB is seeded with a constant (its 5489 or 0 depending on context for reasons unknown). When doing simulations, however, we might want to change this as not to get the same outcome of our experiments each and every time.
