Detailed Description

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

Class representing a subset of a vector space shaped like a hypercube.

This class is determined by a collection of upper and lower limits of the hypercube. (line segment in $ R $ , rectangle in $ R^2 $ , and so on).

template<class V, class M>

QUESO::BoxSubset< V, M >::BoxSubset	(	const char *	prefix,
		const VectorSpace< V, M > &	vectorSpace,
		const V &	minValues,
		const V &	maxValues
	)

Shaped, default constructor.

Construct a subspace of vectorSpace, with min and max values given by the vectors minValues and maxValues, respectively. It checks for possible inconsistencies between the values stored in minValues and maxValues, and calculates the volume of the box subset, assigning it to m_volume.

bool QUESO::BoxSubset< V, M >::contains ( const V & vec ) const

virtual

Checks whether this box subset contains vector vec.

It checks if both statements are true: 1) all components in vec are larger than m_minValues, and 2) all all components in vec are smaller than m_maxValues.

Implements QUESO::VectorSubset< V, M >.
