Random variable with log-normal distribution

Hi,
I need to calculate a random variable with log-normal distribution with zero mean and standard deviation of 4 dB.
How can I do this?
I've tried
lognrnd(0,16)
But can give values to high or to low., and I don't want that, it should be something like 6, 8, 2 dB I guess.

Try this:
v = lognrnd(0, db2mag(4), [1,7]) % Convert 4dB’ To Magnitude, Then Calculate
vdB = db(v2) % Convert Results To dB’
.

@ Star Strider...I am using linear scale for my simulations. Can is use "v" directly in my formula?
