ExtendedKalmanFilterHistory ()

ExtendedKalmanFilterHistory (SequentialFilter *_ptr_filter)

Only one constructor. (No empty constructor.) Builds an empty history for the filter instance passed in as a pointer.

virtual ~ExtendedKalmanFilterHistory ()

virtual void AppendHistory (const double &_appendTime)

Add the filters's data, which occured at a time in seconds, to the history.

virtual void AppendHistory (const ssfTime &_appendTime)

Add the filters's data, which occured at a time in ssfTime form, to the history.

virtual vector< ssfTime
>::difference_type AppendHistory (const vector< ssfTime > &_appendTime)

Add a vector of ssfTime objects to the stored history.

void ResetHistory ()

Erases the sequential filters's struct history.

Matrix GetHistory ()

Returns a matrix of the filter's basic history (no Kalman information).

void GetKalmanHistory (Matrix &_sfHistMatrix, Matrix &_kfHistMatrix)

virtual Vector GetIterationHistory ()

virtual void SetInterpolator (Interpolator *_newInterpolator)

Returns the nearest stored,lower mesh point to the requested time. Sets the interpolator used for calculating the states in-between stored mesh points.

Protected Member Functions

void InitializeSequentialFilterHistory (SequentialFilter *_ptr_filter)

Protected initializer function. A pseudo-constuctor for this abstract class, if you will. Takes a pointer to the filter being logged; called from dervied class constructor.

vector< ssfTime >::difference_type GetState (const ssfTime &_requestedTime)

Returns the nearest stored,lower mesh point to the requested time.

Protected Attributes

vector< Matrix > m_kfCovarianceHistory

internal vector container of covariance matrices, P.

vector< Matrix > m_kfKalmanGainHistory

internal vector container of Kalman gain matrices, K.

SequentialFilter * m_ptr_filter

Pointer to the filter that the history is logging. Note that because this is a pointer to a base class it can be used to point to an instance of any derived class.

vector< ssfTime > m_TimeHistory

internal vector container of the ssfTime objects describing the state history

Interpolator * m_OriginalInterpolator

internal storage of the original, nominal interpolator to be copied and used for all interpolations

vector< Interpolator * > m_TimeInterpolations

internal vector of time interpolations

vector< ssfTime >::difference_type O_SESSAME::History::AppendHistory ( const vector< ssfTime > & _appendTime ) [virtual, inherited]

Add a vector of ssfTime objects to the stored history.
if the beginning of the new time vector is earlier than any of the stored values then the time history will be erased from the overlap point and the new time vector will be appended.
Parameters:

_appendTime vector of ssfTime objects to be appended.

Definition at line 40 of file History.cpp.
References O_SESSAME::History::m_TimeHistory.

void KalmanFilterHistory::AppendHistory ( const ssfTime & _appendTime ) [virtual, inherited]

Add the filters's data, which occured at a time in ssfTime form, to the history.
Appends the state at t=_appendTime. if the new state occured at a time that is earlier than any of the stored values then the time history will be erased from the overlap point and the new state will be appended.
Parameters:

_appendTime the ssfTime object specifying when the state occured, t.

void KalmanFilterHistory::AppendHistory ( const double & _appendTime ) [virtual, inherited]

Add the filters's data, which occured at a time in seconds, to the history.
Appends the state at t=_appendTime. if the new state occured at a time that is earlier than any of the stored values then the time history will be erased from the overlap point and the new state will be appended.
Parameters:

_appendTime time (in seconds) to be added, t.

Matrix KalmanFilterHistory::GetHistory ( ) [virtual, inherited]

Returns a matrix of the filter's basic history (no Kalman information).

Returns:
This function returns a matrix in the form [t_k, state(t_k), control(t_k), measurement(t_k), parameter(t_k)]

void KalmanFilterHistory::GetKalmanHistory ( Matrix & _sfHistMatrix,

Matrix & _kfHistMatrix

) [virtual, inherited]

Returns basic and Kalman history data by reference.

Returns:
This function returns a void but passes the default history and additional Kalman Filter history information by reference in two separate matrices.
The first matrix has (num time steps) rows and is of the form [t_k, state(t_k), control(t_k), measurement(t_k), parameter(t_k)]. The second matrix has (num time steps)*(num states) rows and (num states + num measurements) columns; data is stored as [ P(t_k), K(t_k) ]. Note that each matrix takes up (num states) rows.
Implements SequentialFilterHistory.
