TransversalEventLinearization

eqiora::time

Struct TransversalEventLinearization 

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

Lowered first-order linearization of one isolated transversal event.

This object contains no root selection, event ordering, or reset-solving policy. Those belong to the canonical hybrid scheduler and its lowering. It only composes already-lowered f^-, f^+, guard, and reset actions into event-time and saltation derivatives.

Implementations§

§

impl TransversalEventLinearization

Signature links:§TransversalEventLinearization

pub fn new( flow: EventFlowLinearization, guard: EventGuardLinearization, reset: EventResetLinearization, ) -> Result<TransversalEventLinearization, Diagnostic>

Signature links:newEventFlowLinearizationEventGuardLinearizationEventResetLinearizationResultTransversalEventLinearizationDiagnostic

Compose one mathematically transversal event linearization.

The transversality denominator is g_t + g_y f^-. An exactly zero denominator is a grazing event and fails closed; no hidden numerical tolerance or event-selection rule is introduced here.

§Errors

Returns EQ0704 for shape mismatch, non-finite arithmetic, or grazing.

pub fn state_dimension(&self) -> usize

Signature links:state_dimensionusize

Scalar state dimension.

pub fn parameter_dimension(&self) -> usize

Signature links:parameter_dimensionusize

Number of selected Parameter coordinates.

pub const fn transversality(&self) -> f64

Signature links:transversalityf64

Non-zero transversality denominator g_t + g_y f^-.

pub const fn flow(&self) -> &EventFlowLinearization

Signature links:flowEventFlowLinearization

Flow derivatives used by the event linearization.

pub const fn guard(&self) -> &EventGuardLinearization

Signature links:guardEventGuardLinearization

Guard derivatives used by the event linearization.

pub const fn reset(&self) -> &EventResetLinearization

Signature links:resetEventResetLinearization

Reset derivatives used by the event linearization.

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

Signature links:saltation_matrixf64

Complete row-major saltation matrix.

pub fn propagate_forward( &self, pre_state_sensitivity: &[f64], ) -> Result<EventForwardSensitivity, Diagnostic>

Signature links:propagate_forwardf64ResultEventForwardSensitivityDiagnostic

Propagate fixed-time pre-event forward sensitivities across the event.

Input and returned state sensitivities are row-major (state, Parameter). Event-time sensitivities follow Parameter order.

§Errors

Returns EQ0704 for shape mismatch or non-finite input/output.
