Public Member Functions
double	kalmanStep (genfit::MeasuredStateOnPlane &measuredStateOnPlane, const genfit::MeasurementOnPlane &measurementOnPlane) const
	Kalman update of the mSoP using the measurement. Is just a wrapper around the other kalmanStepper working with bare matrices.
double	calculateResidual (const genfit::MeasuredStateOnPlane &measuredStateOnPlane, const genfit::MeasurementOnPlane &measurementOnPlane) const
	Helper function to calculate a residual between the mSoP and the measurement.

Private Types
using	MeasurementState = Eigen::Matrix< double, Dimension, 1 >
	Matrix class Dimension x 1.
using	MeasurementCovariance = Eigen::Matrix< double, Dimension, Dimension >
	Matrix class Dimension x Dimension.
using	HMatrix = Eigen::Matrix< double, Dimension, 5 >
	Matrix class Dimension x 5.
using	TrackState = Eigen::Matrix< double, 5, 1 >
	Matrix class 5 x 1.
using	TrackCovariance = Eigen::Matrix< double, 5, 5 >
	Matrix class 5 x 5.

Private Member Functions
double	kalmanStep (TrackState &x_k, TrackCovariance &C_k, const MeasurementState &m_k, const MeasurementCovariance &V_k, const HMatrix &H_k) const
	This now is the real "update" step, where we update the X_k and the C_k.

Detailed Description

template<unsigned int Dimension>
class Belle2::KalmanStepper< Dimension >

Class to bundle all algorithms needed for the kalman update procedure.

Its main functionality is to update a measured state on plane with a measurement on plane from a hit using the Kalman procedure described in https://doi.org/10.1016/0168-9002(87)90887-4.

Template Parameters

Dimension

The dimension of the hit - e.g. how many Kalman state parameters are defined by the hits. This defines the size of the matrices.
