Detailed Description

template<class V = GslVector, class M = GslMatrix>
class QUESO::GenericVectorRealizer< V, M >

A class for handling sampling from generic probability density distributions.

A realizer is an object that, simply put, contains a realization() operation that returns a sample of a vector RV, or, particularly, a generic probability density distribution. This is the class that handles generic sampling, used, for example, to sample, posterior PDFs (the solution of a Bayesian problem).

Constructor & Destructor Documentation

template<class V , class M >

QUESO::GenericVectorRealizer< V, M >::GenericVectorRealizer	(	const char *	prefix,
		const VectorSet< V, M > &	unifiedImageSet,
		unsigned int	subPeriod,
		double(*)(const void *routineDataPtr, V &nextParamValues)	routinePtr,
		const void *	routineDataPtr
	)

Default constructor.

Constructs a new object, given a prefix and the image set of the vector realizer, the sub period for the realizations and a pointer to a generic routine.
