Struct Reduction 

pub(super) struct Reduction {
    pub(super) rows: [[f64; 3]; 3],
    pub(super) dual: [[f64; 3]; 3],
}

A reduced basis U rows of lattice rows from geometry::reduce_basis: the integer rows of U and of its inverse transpose W, stored exactly as f64. Ewald shells of a skewed basis are far from Euclidean shells and can stop before short vectors with large indices; shells of the reduced basis cannot.

Fields

rows: [[f64; 3]; 3]

dual: [[f64; 3]; 3]

Implementations

impl Reduction

fn new(rows: [[f64; 3]; 3], dim: usize) -> Option<Self>

pub(super) fn round( reduction: Option<&Self>, fractional: [f64; 3], dim: usize, ) -> [f64; 3]

Reduced-basis coordinates of the lattice point nearest to the point with coordinates fractional in the given basis, rounding in reduced coordinates. None stands for a given basis that is already reduced.

pub(super) fn given( reduction: Option<&Self>, reduced: [f64; 3], dim: usize, ) -> [f64; 3]

Given-basis coordinates U^T c of a point with reduced coordinates c. None stands for a given basis that is already reduced, where both coincide.

Trait Implementations

impl Clone for Reduction

fn clone(&self) -> Reduction

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Reduction

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

Formats the value using the given formatter.

impl Copy for Reduction
