Hi,

I would like to know how is possible to generate random draws from a normal distribution , where the rv has a specific range.

say within a closed interval [-5, 5].

Thanks

Well this would no longer be statistically normally distributed as the support is infinite.

True, I modified my question to be more precise.

Considering that:

p = normpdf([-5, 5], 0, 1)

produces:

p =
       1.4867e-006     1.4867e-006

so the randn function will produce normally-distributed random variables on the interval (-5,+5) with a probability of about 0.999997 or so.
