Struct sprs_rand::rand_distr::Exp
source · [−]pub struct Exp<N> { /* private fields */ }
Expand description
The exponential distribution Exp(lambda)
.
This distribution has density function: f(x) = lambda * exp(-lambda * x)
for x > 0
.
Note that Exp1
is an optimised implementation for lambda = 1
.
Example
use rand_distr::{Exp, Distribution};
let exp = Exp::new(2.0).unwrap();
let v = exp.sample(&mut rand::thread_rng());
println!("{} is from a Exp(2) distribution", v);

from the equivalent element of its
superset. Read more

Checks if self
is actually part of its subset T
(and can be converted to it).

unsafe fn to_subset_unchecked(&self) -> SS
Use with care! Same as self.to_subset
but without any property checks. Always succeeds.
