Struct Laplace 

pub struct Laplace { /* private fields */ }

Laplace Distribution

Example

let mut laplace = rand_simple::Laplace::new(1192u32);
assert_eq!(format!("{laplace}"), "La(Location parameter, Scale parameter) = La(0, 1)");
println!("Returns a random number -> {}", laplace.sample());

// Modify the distribution's parameters
let location: f64 = -2f64;
let scale: f64 = 1.5f64;
let result: Result<(f64, f64), &str> = laplace.try_set_params(location, scale);
assert_eq!(format!("{laplace}"), "La(Location parameter, Scale parameter) = La(-2, 1.5)");
println!("Returns a random number -> {}", laplace.sample());

Implementations

impl Laplace

pub fn new(_seed: u32) -> Self

Constructor

• _seed - Random seed to initialize the generator.

pub fn sample(&mut self) -> f64

Calculate a random number.

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

Modify the parameters of the random variable.

• location - Location parameter
• scale - Scale parameter

Trait Implementations

impl Display for Laplace

Formatter for displaying with macros like println!

• Location parameter
• Scale parameter

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

Formats the value using the given formatter.
