Struct SparseSolver 

pub struct SparseSolver { /* private fields */ }

A sparse direct solver for repeated solves on a fixed sparsity pattern.

Cloning shares the cached factorization, whose pivot order and fill pattern are reused across solves until a pivot degrades. Symmetric values use an LDLᵀ factorization, falling back to LU otherwise. Symmetry is a caller-supplied guarantee about the source values, not detected at runtime — a source whose symmetry can vary between solves (e.g. a tangent that is only symmetric near a particular configuration) must be declared asymmetric.

Implementations

impl SparseSolver

pub fn from_pattern( num: usize, pattern: Vec<(usize, usize)>, symmetric: bool, ) -> Self

pub fn pattern(&self) -> Ref<'_, [(usize, usize)]>

The nonzero (row, column) positions this structure was built from.

pub fn solve( &self, source: impl FnMut(usize, usize) -> Scalar, b: &Vector, ) -> Result<Vector, SparseError>

Solve a system of linear equations with values from a source, refactoring the cached factorization when possible.

Trait Implementations

impl Clone for SparseSolver

fn clone(&self) -> SparseSolver

Returns a duplicate of the value.

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

Performs copy-assignment from source.
