Detailed Description

template<typename T>
class BFL::SystemModel< T >

Template class representing all possible (continu and discrete) System Models

Todo:

Check if there should be a "model" base class...

Bug:

Currently supports only systemmodels of the form P(x | x, u), where both u and x are continu or discrete. So it lacks support for mixed systems () and systems with extra parameters. You are welcome to provide an API and implementation for this :-)

Member Function Documentation

Probability ProbabilityGet	(	const T &	x_k,
		const T &	x_kminusone
	)			[inline]

Get the probability of arriving in a next state.

(no-input-system)

Parameters:

	x_k	the next state (at time k)
	x_kminusone	the current state (at time k-1)

Returns:

the probability value

Definition at line 312 of file systemmodel.h.

Probability ProbabilityGet	(	const T &	x_k,
		const T &	x_kminusone,
		const T &	u
	)			[inline]

Get the probability of arriving in a next state.

Parameters:

	x_k	the next state (at time k)
	x_kminusone	the current state (at time k-1)
	u	the input

Returns:

the probability value

Definition at line 302 of file systemmodel.h.

T Simulate	(	const T &	x,
		int	sampling_method = DEFAULT,
		void *	sampling_args = NULL
	)			[inline]

Simulate the system (no input system).

Parameters:

x

current state of the system

Returns:

State where we arrive by simulating the system model for 1 step

Note:

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

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)

Definition at line 290 of file systemmodel.h.

T Simulate	(	const T &	x,
		const T &	u,
		int	sampling_method = DEFAULT,
		void *	sampling_args = NULL
	)			[inline]

Simulate the system.

Parameters:

	x	current state of the system
	u	input to the system

Returns:

State where we arrive by simulating the system model for 1 step

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<T> instead of a T

int StateSizeGet

(

)

const [inline]

Get State Size.

Copy constructor SystemModel(const SystemModel<T>& model);

Definition at line 230 of file systemmodel.h.

ConditionalPdf< T, T > * SystemPdfGet

(

)

[inline]

ConditionalPdf< T, T > *

pdf

)

[inline]

Set the SystemPDF.

Parameters:

pdf

a reference to the ConditionalPdf describing the system
