Dear colleagues,
I'm trying to select samples from a normal distribution (with
parameters mu, sigma), belonging to a certain "alphabet". For
instance, we have the normal N(0,1), but we want the outcome to
belong in the set [0,1,...,N].
Do you know how to do this? (I think that the functions randn,
normrnd are not appopriate by themselves)

Thank you very much in advance

What exactly do you mean? The normal distribution is a continuous
distribution on the whole real line. You want values in a finite
set. So it will be a discrete distribution, not a normal
distribution. What distribution do you really want?
