Member Function Documentation

Probability ProbabilityGet ( const int &  x_k, const int &  x_kminusone, const int &  u  )

inherited

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

Probability ProbabilityGet ( const int &  x_k, const int &  x_kminusone  )

inherited

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

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

inherited

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 Simulate ( const int &  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 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)

int StateSizeGet ( ) const

inherited

Get State Size.

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

Returns

the statesize of the system

ConditionalPdf<int ,int >* SystemPdfGet ( )

inherited

Get the SystemPDF.

Returns

a reference to the ConditionalPdf describing the system

void SystemPdfSet ( ConditionalPdf< int , int > *  pdf )

inherited

Set the SystemPDF.

Parameters

pdf	a reference to the ConditionalPdf describing the system
