Struct sprs_rand::rand::distributions::StandardNormal
source · [−]pub struct StandardNormal;
moved to rand_distr crate
Expand description
Samples floating-point numbers according to the normal distribution
N(0, 1)
(a.k.a. a standard normal, or Gaussian). This is equivalent to
Normal::new(0.0, 1.0)
but faster.
See Normal
for the general normal distribution.
Implemented via the ZIGNOR variant1 of the Ziggurat method.

The inverse inclusion map: attempts to construct self
from the equivalent element of its
superset. Read more
fn is_in_subset(&self) -> bool

Checks if self
is actually part of its subset T
(and can be converted to it).
unsafe fn to_subset_unchecked(&self) -> SS
unsafe fn to_subset_unchecked(&self) -> SS
Use with care! Same as self.to_subset
but without any property checks. Always succeeds.

The inclusion map: converts self
to the equivalent element of its superset.
