Struct rand::distributions::normal::Normal
[−]
[src]
pub struct Normal { /* fields omitted */ }The normal distribution N(mean, std_dev**2).
This uses the ZIGNOR variant of the Ziggurat method, see
StandardNormal for more details.
Example
use rand::distributions::{Normal, IndependentSample}; // mean 2, standard deviation 3 let normal = Normal::new(2.0, 3.0); let v = normal.ind_sample(&mut rand::thread_rng()); println!("{} is from a N(2, 9) distribution", v)Run
Methods
impl Normal[src]
fn new(mean: f64, std_dev: f64) -> Normal
Construct a new Normal distribution with the given mean and
standard deviation.
Panics
Panics if std_dev < 0.
