Member Function Documentation

virtual MatrixWrapper::Matrix df_dxGet	(	const MatrixWrapper::ColumnVector &	u,
		const MatrixWrapper::ColumnVector &	x
	)			[virtual]

Returns H-matrix.

used by extended kalman filter

Parameters:

	u	The value of the input in which the derivate is evaluated
	x	The value in the state in which the derivate is evaluated

Reimplemented in LinearAnalyticMeasurementModelGaussianUncertainty, LinearAnalyticMeasurementModelGaussianUncertainty_Implicit, and NonLinearAnalyticMeasurementModelGaussianUncertainty_Ginac.

void MeasurementPdfSet

(

ConditionalPdf< MatrixWrapper::ColumnVector , MatrixWrapper::ColumnVector > *

pdf

)

[inherited]

Set the MeasurementPDF.

Parameters:

pdf

a pointer to the measurement pdf

Probability ProbabilityGet	(	const MatrixWrapper::ColumnVector &	z,
		const MatrixWrapper::ColumnVector &	x
	)			[inherited]

Get the probability of a certain measurement.

(measurement independent of input) gived a certain state and input

Parameters:

	z	the measurement value
	x	x current state of the system

Returns:

the "probability" of the measurement

Probability ProbabilityGet	(	const MatrixWrapper::ColumnVector &	z,
		const MatrixWrapper::ColumnVector &	x,
		const MatrixWrapper::ColumnVector &	s
	)			[inherited]

Get the probability of a certain measurement.

given a certain state and input

Parameters:

	z	the measurement value
	x	current state of the system
	s	the sensor param value

Returns:

the "probability" of the measurement

MatrixWrapper::ColumnVector Simulate	(	const MatrixWrapper::ColumnVector &	x,
		int	sampling_method = DEFAULT,
		void *	sampling_args = NULL
	)			[inherited]

Simulate the system (no input system).

Parameters:

x

current state of the system

Returns:

State where we arrive by simulating the measurement model

Note:

Maybe the return value would better be a Sample<StateVar> instead of a StateVar

Parameters:

	sampling_method	the sampling method to be used while sampling from the Conditional Pdf describing the system (if not specified = DEFAULT)
	sampling_args	Sometimes a sampling method can have some extra parameters (eg mcmc sampling)

MatrixWrapper::ColumnVector Simulate	(	const MatrixWrapper::ColumnVector &	x,
		const MatrixWrapper::ColumnVector &	s,
		int	sampling_method = DEFAULT,
		void *	sampling_args = NULL
	)			[inherited]

Simulate the Measurement, given a certain state, and an input.

Parameters:

	x	current state of the system
	s	sensor parameter

Returns:

Measurement generated by simulating the measurement model

Parameters:

	sampling_method	the sampling method to be used while sampling from the Conditional Pdf describing the system (if not specified = DEFAULT)
	sampling_args	Sometimes a sampling method can have some extra parameters (eg mcmc sampling)

Note:

Maybe the return value would better be a Sample<StateVar> instead of a StateVar
