Hi,
I want to generate a set of 50 random variable having std_deviation 0.1 and mean 0.5 from a normal distribution...it can be float
but I want to generate 50 random integers with std_deviation 3500 and mean 4000..
how to do the both with
randn?

help randn
will tell you how to generate a set with a given mean and variance. Why not read the help? Or take a basic class in probability & statistics.
As for integers, you cannot do so. A normal distribution is CONTINUOUS. That says your question has no meaning in mathematics.
You can generate integers that are APPROXIMATELY normally distributed. Round will do that for you here.
