◆ AnalyticMeasurementModelGaussianUncertainty()

AnalyticMeasurementModelGaussianUncertainty ( AnalyticConditionalGaussian * Measurementpdf = NULL )

Constructor.

Parameters

Measurementpdf ConditionalPdf<S,T> representing $P(Z_k | X_{k} (, U_{k}))$

See also: MEASUREMENT_SIZE, STATE_SIZE, INPUT_SIZE, _MeasurementPdf

Member Function Documentation

◆ df_dxGet()

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

virtual

Returns H-matrix.

$H = \frac{df}{dx} \mid_{u,x}$

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 NonLinearAnalyticMeasurementModelGaussianUncertainty_Ginac, LinearAnalyticMeasurementModelGaussianUncertainty_Implicit, and LinearAnalyticMeasurementModelGaussianUncertainty.

◆ MeasurementPdfSet()

void MeasurementPdfSet ( ConditionalPdf< MatrixWrapper::ColumnVector , MatrixWrapper::ColumnVector > * pdf )

inherited

Set the MeasurementPDF.

Parameters

pdf	a pointer to the measurement pdf

Definition at line 96 of file measurementmodel.h.

◆ ProbabilityGet() [1/2]

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

Definition at line 151 of file measurementmodel.h.

◆ ProbabilityGet() [2/2]

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

Definition at line 162 of file measurementmodel.h.

◆ Simulate() [1/2]

MatrixWrapper::ColumnVector Simulate	(	const MatrixWrapper::ColumnVector &	x,
		const MatrixWrapper::ColumnVector &	s,
		const SampleMthd	sampling_method = `SampleMthd::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

Definition at line 122 of file measurementmodel.h.

◆ Simulate() [2/2]

MatrixWrapper::ColumnVector Simulate	(	const MatrixWrapper::ColumnVector &	x,
		const SampleMthd	sampling_method = `SampleMthd::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)
