Enum NormalRecipe 

pub enum NormalRecipe {
    SppWeightedResidualFiniteDifference,
    RtkDoubleDifferenceBlockFirstTie,
    PppDenseLastTie,
    CanonicalSquareRoot,
}

Normal-equation assembly tie-breaking / fold order. The tie order is the pivot/elimination convention that fixes the bit pattern of the reduced system.

Variants

SppWeightedResidualFiniteDifference

SPP weighted-residual rows with a finite-difference design matrix (spp least-squares).

RtkDoubleDifferenceBlockFirstTie

RTK double-difference block assembly with the first-tie covariance fold (rtk_filter::normal first-tie block).

PppDenseLastTie

PPP dense normal equations with the last-tie solve (precise_positioning::normal *_last_tie).

CanonicalSquareRoot

Canonical square-root-information solve, shared by canonical RTK and canonical PPP: the SPD normal system is solved by the owned deterministic Cholesky factorization Λ = L Lᵀ plus forward/back substitution, where L is the information-matrix square root. For RTK this is the double-difference information system Λ x = η assembled by the same shared block fold the RTK reference uses; for PPP it is the dense weighted normal system AᵀWA x = AᵀWy assembled from the same undifferenced rows the PPP reference uses. This is the numerically rigorous op-order for an SPD normal matrix (no pivoting; exploits symmetry), distinct from the reference RTK general first-tie Gaussian elimination (Self::RtkDoubleDifferenceBlockFirstTie) and the reference PPP last-tie Gaussian elimination (Self::PppDenseLastTie). Driven by EstimationRecipe::canonical_rtk and EstimationRecipe::canonical_ppp on the owned SolverRecipe::OwnedDeterministicCholesky kernel; not used by any reference strategy.

Trait Implementations

impl Clone for NormalRecipe

fn clone(&self) -> NormalRecipe

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for NormalRecipe

impl Debug for NormalRecipe

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

Formats the value using the given formatter.

impl Default for NormalRecipe

fn default() -> NormalRecipe

Returns the “default value” for a type.

impl Eq for NormalRecipe

impl Hash for NormalRecipe

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for NormalRecipe

fn eq(&self, other: &NormalRecipe) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
