[−][src]Struct sprs_rand::rand_distr::Normal
The normal distribution N(mean, std_dev**2)
.
This uses the ZIGNOR variant of the Ziggurat method, see StandardNormal
for more details.
Note that StandardNormal
is an optimised implementation for mean 0, and
standard deviation 1.
Example
use rand_distr::{Normal, Distribution}; // mean 2, standard deviation 3 let normal = Normal::new(2.0, 3.0).unwrap(); let v = normal.sample(&mut rand::thread_rng()); println!("{} is from a N(2, 9) distribution", v)
