Generate white noise with amplitude between [-1 1] with Matlab

Question

I\'m using the Matlab function Y = WGN(M,N,P) to generate white noise with Gaussian distribution. This function uses a power value (dB Watts) to calculate the

Answer 1

why you just take randn function of whatever bound and then just normalize it like this ex.

 noise=randn(400); noise=noise./max(max(noise)); 

so whatever is the output of randn finally you will have a w.n. inside [-1 1].
