Struct Lu 

pub(crate) struct Lu {
    factors: DMatrix<Complex>,
    permutation: Perm<usize>,
    equilibration: Option<Equilibration>,
}

Packed pivoted LU: overwrite the operator and share its triangular storage.

Fields

factors: DMatrix<Complex>

permutation: Perm<usize>

equilibration: Option<Equilibration>

Implementations

impl Lu

pub(crate) fn state_size(n: usize) -> Result<usize>

Bytes for factors, forward permutation, and canonical row/column scales.

pub(crate) fn write_state(&self, writer: &mut Writer)

Write numerical factors without refactorizing their operator.

pub(crate) fn read_state(reader: &mut Reader<'_>, n: usize) -> Result<Self>

Restore numerical factors; the containing record provides the dimension.

impl Lu

pub(crate) fn new(factors: DMatrix<Complex>) -> Result<Self>

pub(crate) fn solve_in_place(&self, rhs: MatMut<'_, Complex>) -> Result<()>

Solve A X = B in place, with A the operator given to Lu::new.

pub(crate) fn solve_adjoint_in_place( &self, rhs: MatMut<'_, Complex>, ) -> Result<()>

Solve Aᴴ X = B in place.

fn solve_with(&self, rhs: MatMut<'_, Complex>, adjoint: bool) -> Result<()>

Trait Implementations

impl Clone for Lu

fn clone(&self) -> Lu

Returns a duplicate 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.
