Struct SymbolicFactorization 

pub struct SymbolicFactorization {
    pub etree: EliminationTree,
    pub structure: SupernodalStructure,
    pub nnz_l: usize,
    pub nnz_u: usize,
}

Reusable symbolic factorization for repeated numeric factorizations with the same sparsity pattern.

Fields

etree: EliminationTree

The elimination tree.

structure: SupernodalStructure

The supernodal structure.

nnz_l: usize

Estimated non-zeros in L.

nnz_u: usize

Estimated non-zeros in U (same as nnz_l for Cholesky).

Implementations

impl SymbolicFactorization

pub fn compute( row_offsets: &[usize], col_indices: &[usize], n: usize, ) -> Result<Self, SolverError>

Perform symbolic factorization from CSR structure (lower triangle).

Trait Implementations

impl Clone for SymbolicFactorization

fn clone(&self) -> SymbolicFactorization

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SymbolicFactorization

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

Formats the value using the given formatter.
