Struct Lu

pub struct Lu { /* private fields */ }

P A = L U with partial pivoting.

Implementations

impl Lu

pub fn new(a: &Matrix) -> NumericResult<Self>

Factor a square matrix.

Errors

Refuses a non-square or non-finite matrix, and a matrix singular to working precision (a zero pivot, or a condition estimate above 1 / eps).

pub fn condition_estimate(&self) -> f64

Estimate of the 1-norm condition number ||A||_1 ||A^-1||_1. It is a lower bound, in practice within a factor of 3.

pub fn solve(&self, b: &[f64]) -> NumericResult<LinearSolution>

Solve A x = b.

Errors

Refuses b of the wrong length or with non-finite entries.

Trait Implementations

impl Clone for Lu

fn clone(&self) -> Lu

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Lu

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

Formats the value using the given formatter.

impl PartialEq for Lu

fn eq(&self, other: &Lu) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
