Detailed Description

Threshold-based filter.

Constructor & Destructor Documentation

template<class ScalarType >

RBGen::ThreshFilter< ScalarType >::ThreshFilter	(	SortType	which,
		bool	absthresh,
		typename Teuchos::ScalarTraits< ScalarType >::magnitudeType	thresh
	)

inline

Default constructor.

The threshold definition depends on which:

LARGEST: value cand passes the filter if $cand \geq tval$
SMALLEST: value cand passes the filter if $cand \leq tval$ where tval depends on absthresh:
false:
- $tval \doteq thresh \cdot max(svals)$
- $tval \doteq thresh \cdot min(svals)$
true: $tval \doteq thresh$
