Struct LinearProblem 

pub struct LinearProblem<'a> { /* private fields */ }
Description

One validated host-local linear problem.

Implementations§

§

impl<'a> LinearProblem<'a>

Signature links:§LinearProblem

pub fn new( operator: &'a dyn LinearOperator, right_hand_side: &'a [f64], properties: LinearOperatorProperties, ) -> Result<LinearProblem<'a>, Diagnostic>

Signature links:newLinearOperatorf64LinearOperatorPropertiesResultLinearProblemDiagnostic

Construct a square problem with an implicit zero initial guess.

§Errors

Returns EQ0802 for empty/non-square shape, right-hand-side mismatch, or non-finite data.

pub fn with_initial_guess( self, initial_guess: &'a [f64], ) -> Result<LinearProblem<'a>, Diagnostic>

Signature links:with_initial_guessf64ResultLinearProblemDiagnostic

Attach an explicit initial guess.

§Errors

Returns EQ0802 for a shape mismatch or non-finite value.

pub const fn operator(&self) -> &'a dyn LinearOperator

Signature links:operatorLinearOperator

Operator action.

pub const fn right_hand_side(&self) -> &'a [f64]

Signature links:right_hand_sidef64

Right-hand-side values.

pub const fn initial_guess(&self) -> Option<&'a [f64]>

Signature links:initial_guessOptionf64

Explicit initial guess, or None for the zero vector.

pub const fn properties(&self) -> LinearOperatorProperties

Signature links:propertiesLinearOperatorProperties

Asserted mathematical properties.

pub const fn canonical_csr_system(&self) -> Option<&'a CanonicalCsrSystemView>

Signature links:canonical_csr_systemOptionCanonicalCsrSystemView

Exact captured CSR coefficient source associated with this problem.

The problem right-hand side may be derivative-specific and therefore differ from the source’s captured primal right-hand side. Hand-built problems return None; a backend requiring materialized sparse storage must fail closed in that case.
