[−][src]Struct nannou::rand::distributions::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::distributions::{Normal, Distribution}; // mean 2, standard deviation 3 let normal = Normal::new(2.0, 3.0); let v = normal.sample(&mut rand::thread_rng()); println!("{} is from a N(2, 9) distribution", v)
Methods
impl Normal
[src]
pub fn new(mean: f64, std_dev: f64) -> Normal
[src]
Construct a new Normal
distribution with the given mean and
standard deviation.
Panics
Panics if std_dev < 0
.
