Struct LuFactorization 

pub struct LuFactorization {
    pub n: usize,
    pub lu: Vec<f32>,
    pub pivot: Vec<usize>,
}

LU factorization result (in-place: L and U stored in the same matrix).

After factorization, the matrix a contains:

• Upper triangle (including diagonal): U
• Strict lower triangle: L (unit diagonal implicit)

Fields

n: usize

Row dimension.

lu: Vec<f32>

Factored matrix (L\U packed).

pivot: Vec<usize>

Pivot indices: row i was swapped with row pivot[i].

Implementations

impl LuFactorization

pub fn solve(&self, b: &[f32]) -> Result<Vec<f32>, SolverError>

Solve Ax = b using the LU factorization.

Contract: solve-lu-v1.yaml / solution_accuracy

Errors

Returns error on dimension mismatch.

pub fn extract_l(&self) -> Vec<f32>

Extract L matrix (unit lower triangular).

pub fn extract_u(&self) -> Vec<f32>

Extract U matrix (upper triangular).

pub fn extract_p(&self) -> Vec<f32>

Extract permutation matrix.

Trait Implementations

impl Debug for LuFactorization

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

Formats the value using the given formatter.

impl Solver for LuFactorization

fn solve(&self, b: &[f32]) -> Result<Vec<f32>, SolverError>

Solve Ax = b using this factorization.

fn dimension(&self) -> usize

Matrix dimension (n for n×n systems, or min(m,n) for rectangular).
