Detailed Description

Stateful wrapper around computeBetaBatch / computeGammaBatch.

Maintains a session-scoped running_max so callers do not need to manage it manually. Existing call sites that use RelativisticSignalProcessor can migrate by:

// Before (scalar):
double rmax = 0.0;
auto betas  = scalar_beta_batch(velocities, rmax);
auto gammas = scalar_gamma_batch(betas);
 
// After (SIMD-dispatched, same semantics):
BetaCalculator calc;
auto betas  = calc.computeBetaBatch(velocities);
auto gammas = calc.computeGammaBatch(betas);

NOT thread-safe. Create one BetaCalculator per thread.

Constructor & Destructor Documentation

BetaCalculator()

srfm::simd::BetaCalculator::BetaCalculator ( )

noexcept

Construct a fresh calculator. running_max starts at 0.0.

Examples

/home/runner/work/Special-Relativity-in-Financial-Modeling/Special-Relativity-in-Financial-Modeling/include/srfm/simd/simd_dispatch.hpp.

Definition at line 151 of file simd_dispatch.cpp.

Member Function Documentation

computeBetaBatch()

std::vector< srfm::momentum::BetaVelocity > srfm::simd::BetaCalculator::computeBetaBatch ( const std::vector< double > &  velocities )

noexcept

Compute β_i = |v_i| / running_max for a batch of velocities.

Delegates to the runtime-selected SIMD kernel. running_max is advanced to include this batch's maximum |velocity|.

Parameters

velocities

Raw price velocities (any finite double).

Returns

One BetaVelocity per velocity, in order.

Examples

/home/runner/work/Special-Relativity-in-Financial-Modeling/Special-Relativity-in-Financial-Modeling/include/srfm/simd/simd_dispatch.hpp.

Definition at line 157 of file simd_dispatch.cpp.

computeGammaBatch()

std::vector< srfm::momentum::LorentzFactor > srfm::simd::BetaCalculator::computeGammaBatch ( const std::vector< srfm::momentum::BetaVelocity > &  betas )

noexcept

Compute γ_i = 1/√(1 − β_i²) for a batch of betas.

Delegates to the runtime-selected SIMD kernel.

Parameters

betas

Output from a previous call to computeBetaBatch().

Returns

One LorentzFactor per beta, in order.

Examples

/home/runner/work/Special-Relativity-in-Financial-Modeling/Special-Relativity-in-Financial-Modeling/include/srfm/simd/simd_dispatch.hpp.

Definition at line 164 of file simd_dispatch.cpp.

reset()

void srfm::simd::BetaCalculator::reset ( )

noexcept

Reset the running maximum to 0.0.

Call between trading sessions to prevent stale state from inflating the denominator and artificially suppressing beta values.

Examples

/home/runner/work/Special-Relativity-in-Financial-Modeling/Special-Relativity-in-Financial-Modeling/include/srfm/simd/simd_dispatch.hpp.

Definition at line 170 of file simd_dispatch.cpp.

running_max()

double srfm::simd::BetaCalculator::running_max ( ) const

noexcept

Returns the current running maximum (read-only).

Examples

/home/runner/work/Special-Relativity-in-Financial-Modeling/Special-Relativity-in-Financial-Modeling/include/srfm/simd/simd_dispatch.hpp.

Definition at line 174 of file simd_dispatch.cpp.

simd_level()

SimdLevel srfm::simd::BetaCalculator::simd_level ( ) const

noexcept

Returns the SIMD level selected for this process.

Examples

/home/runner/work/Special-Relativity-in-Financial-Modeling/Special-Relativity-in-Financial-Modeling/include/srfm/simd/simd_dispatch.hpp.
