Struct HalfNormal 

pub struct HalfNormal { /* private fields */ }

Half Normal Distribution

Example

let mut half_normal = rand_simple::HalfNormal::new([1192_u32, 765_u32]);
assert_eq!(format!("{half_normal}"), "HN(Std^2) = HN(1^2)");
println!("Returns a random number -> {}", half_normal.sample());

// If you want to change the parameters of the random variable
let variance: f64 = 2_f64;
let result: Result<f64, &str> = half_normal.try_set_params(variance);
assert_eq!(format!("{half_normal}"), "HN(Std^2) = HN(2^2)");
println!("Returns a random number -> {}", half_normal.sample());

Implementations

impl HalfNormal

pub fn new(seeds: [u32; 2]) -> Self

Constructor

• seeds - Seeds for random number generation. Adjusted on the constructor side to ensure they are not the same.

pub fn sample(&mut self) -> f64

Generate a random number.

pub fn try_set_params(&mut self, std: f64) -> Result<f64, &'static str>

Modify the parameters of the random variable.

• std - Standard deviation

Trait Implementations

impl Display for HalfNormal

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formatter for displaying in functions like println! macro

• Standard deviation
