Struct SparseLu 

pub struct SparseLu { /* private fields */ }

Implementations

impl SparseLu

pub fn factor_csr( n: usize, offsets: &[usize], columns: &[usize], values: &[f64], options: SparseLuOptions, ) -> Result<Self, SolverError>

Borrow zero-based CSR. Unsorted/duplicate column entries are summed; explicit zeros are removed. offsets must contain n+1 entries and start at zero.

pub fn order(&self) -> usize

pub fn factor_nonzeros(&self) -> usize

pub fn pivots(&self) -> &[usize]

pub fn packed_row(&self, i: usize) -> Option<&BTreeMap<usize, f64>>

Exposes packed factors by sparse row: strict lower L, diagonal/upper U; unit diagonal of L is implicit. No n*n output allocation.

pub fn solve(&self, b: MatrixView<'_>) -> Result<Matrix, SolverError>

pub fn solve_transpose(&self, b: MatrixView<'_>) -> Result<Matrix, SolverError>

Trait Implementations

impl Clone for SparseLu

fn clone(&self) -> SparseLu

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SparseLu

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

Formats the value using the given formatter.
