Struct wee_matrix::LU

pub struct LU<T, P> { /* fields omitted */ }

LU (lower-upper) decomposition structure using value storage type T and permutation storage type P.

Methods

impl LU<Matrix, Vec<usize>>

fn l(&self) -> Matrix

Return the lower-triangular postion of the decomposition. This is a heavy operation: it will generate an entirely new lower-triangular matrix from the decomposition data.

fn u(&self) -> Matrix

Return the upper-triangular postion of the decomposition. This is a heavy operation: it will generate an entirely new upper-triangular matrix from the decomposition data.

fn p(&self) -> Matrix

Return the permutation matrix for the decomposition. This is a heavy operation: it will generate an entirely new matrix from the decomposition and permutation data.

fn lu_data(&self) -> &Matrix

Retrieve a reference to the LU storage matrix itself

fn ipiv_data(&self) -> &Vec<usize>

Retrieve a reference to the permutation data (internally stored as a vector)

fn lu_data_mut(&mut self) -> &mut Matrix

Retrieve a mutable reference to the LU storage matrix itself

fn ipiv_data_mut(&mut self) -> &mut Vec<usize>

Retrieve a mutable reference to the permutation data (internally stored as a vector)
