class GainMatrixSmoother
#include <Acts/TrackFitting/GainMatrixSmoother.hpp>

Kalman trajectory smoother based on gain matrix formalism.

This implements not a single smoothing step, but the full backwards smoothing procedure for a filtered, forward trajectory using the stored linearization.

Public Functions

Result<void> operator()(const GeometryContext &gctx, MultiTrajectory &trajectory, size_t entryIndex, LoggerWrapper logger = getDummyLogger()) const

Run the Kalman smoothing for one trajectory.

Parameters

  • gctx – [in] The geometry context for the smoothing

  • trajectory – [inout] The trajectory to be smoothed

  • entryIndex – [in] The index of state to start the smoothing

  • logger – [in] Where to write logging information to
