Struct rand_simple::Levy

source ·
pub struct Levy { /* private fields */ }
Expand description

レヴィ分布を計算する構造体

使用例 1 (new関数)

use rand_simple::Levy;
let levy = Levy::new(1192u32, 765u32);
let next = levy.sample(); // 位置母数 μ = 0, 尺度母数 θ = 1の標準レヴィ分布
println!("乱数: {}", next); // 0.15611801640551176f64

使用例 2 (マクロ・引数有り)

use rand_simple::create_levy;
let levy = create_levy!(1192u32, 765u32);
let next = levy.sample(); // 位置母数 μ = 0, 尺度母数 θ = 1の標準レヴィ分布
println!("乱数: {}", next); // 0.15611801640551176f64

使用例 3 (マクロ・引数無し)

use rand_simple::create_levy;
let levy = create_levy!();
let next = levy.sample(); // 位置母数 μ = 0, 尺度母数 θ = 1の標準レヴィ分布
println!("乱数: {}", next); // 値不明

Implementations§

source§

impl Levy

source

pub fn new(_seed_1: u32, _seed_2: u32) -> Self

コンストラクタ

  • _seed_1 - 乱数の種
  • _seed_2 - 乱数の種。_seed_1と同じ値の場合、コンストラクタ側で変更する。
source

pub fn sample(&self) -> f64

標準レヴィ分布に従う乱数を返す

  • 位置母数 0
  • 尺度母数 1
