Hi folks,
How do I generate a random noise with zero mean, variance not equal to 1.
randn() is for zero mean, variance=1 case. Thanks,
Mu

Hi Mu,

Try:

noise = mean + variance*randn();

Regards,
Jeff

I think it would be:

noise = mean + sqrt(variance) * randn();

Hi!

You can use the function "normrnd" to generate random numbers
from a distribution with specified mean and
variance!

cheers,

Pradeep.

Jorge,

You think correct. My mistake.
