I know `rand()` will generate a random number following unif(0,1), but how to generate a random number following gaussian distribution? Is there an existing function?

`randn` will generate a number according to the standard normal distribution.

If you want other distributions as well do

```julia
using Distributions

rand(Normal(0,1))
rand(Gamma(3,1))
...etc

```
