Struct rand::distributions::Normal

pub struct Normal { /* fields omitted */ }

👎 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

impl Normal

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.
