class Anasazi::MultiVecTraits< ScalarType, MultiVec< ScalarType > >

Specialization of MultiVecTraits for Belos::MultiVec.

Anasazi interfaces to every multivector implementation through a specialization of MultiVecTraits. Thus, we provide a specialization of MultiVecTraits for the MultiVec run-time polymorphic interface above.

Template Parameters

ScalarType The type of entries in the multivector; the template parameter of MultiVec.
