Struct rand::distributions::Normal

source · [−]

pub struct Normal { /* private fields */ }

👎 Deprecated since 0.7.0:

moved to rand_distr crate

Expand description

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.

Implementations

source

impl Normal

source

pub 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.
