Struct peroxide::structure::matrix::PQLU

pub struct PQLU {
    pub p: Vec<usize>,
    pub q: Vec<usize>,
    pub l: Matrix,
    pub u: Matrix,
}

Data structure for Complete Pivoting LU decomposition

Usage

extern crate peroxide;
use peroxide::fuga::*;

let a = ml_matrix("1 2;3 4");
let pqlu = a.lu();
let (p, q, l, u) = pqlu.extract();
// p, q are permutations
// l, u are matrices
l.print(); // lower triangular
u.print(); // upper triangular

Fields

p: Vec<usize>

q: Vec<usize>

l: Matrix

u: Matrix
