Struct ConstantDerivativeMatrixProof 

pub struct ConstantDerivativeMatrixProof { /* private fields */ }
Description

A constant derivative Jacobian whose rank is computed without a numerical tolerance.

Every finite f64 coefficient is interpreted as the exact binary rational number represented by its bits. Rank is then recomputed with arbitrary- precision rational elimination. The stored rank is therefore evidence about the lowered matrix itself, not a sample-state estimate or a backend-dependent floating-point classification.

Implementations§

§

impl ConstantDerivativeMatrixProof

Signature links:§ConstantDerivativeMatrixProof

pub fn new( dimension: usize, coefficients: Vec<f64>, ) -> Result<ConstantDerivativeMatrixProof, Diagnostic>

Signature links:newusizeVecf64ResultConstantDerivativeMatrixProofDiagnostic

Construct and exactly classify one square constant derivative matrix.

§Errors

Returns EQ0705 for an empty/non-square matrix or a non-finite coefficient.

pub const fn dimension(&self) -> usize

Signature links:dimensionusize

Number of state coordinates and residual rows.

pub fn coefficients(&self) -> &[f64]

Signature links:coefficientsf64

Complete row-major coefficient storage.

pub fn row(&self, row: usize) -> Option<&[f64]>

Signature links:rowusizeOptionf64

One residual row in state-coordinate order.

pub const fn exact_rank(&self) -> usize

Signature links:exact_rankusize

Exact rank over the binary rational values represented by the matrix.

pub fn monomial_rows(&self) -> Option<Vec<MonomialDerivativeRow>>

Signature links:monomial_rowsOptionVecMonomialDerivativeRow

Derive the monomial row view used only for explicit-ODE normalization.

Returns None unless every row has exactly one non-zero coefficient and every state coordinate occurs exactly once.
