Struct ndarray_rand::rand_distr::Triangular

pub struct Triangular<N> { /* fields omitted */ }

The triangular distribution.

A continuous probability distribution parameterised by a range, and a mode (most likely value) within that range.

The probability density function is triangular. For a similar distribution with a smooth PDF, see the Pert distribution.

Example

use rand_distr::{Triangular, Distribution};

let d = Triangular::new(0., 5., 2.5).unwrap();
let v = d.sample(&mut rand::thread_rng());
println!("{} is from a triangular distribution", v);

Methods

    N: Float,
    Standard: Distribution<N>, 

pub fn new(min: N, max: N, mode: N) -> Result<Triangular<N>, TriangularError>

Set up the Triangular distribution with defined min, max and mode.
