Detailed Description

template<class ScalarType, class MV>
class Anasazi::MultiVecTraits< ScalarType, MV >

Virtual base class which defines basic traits for the multi-vector type.

An adapter for this traits class must exist for the MV type. If not, this class will produce a compile-time error.

Examples:

BlockKrylovSchur/BlockKrylovSchurEpetraEx.cpp, BlockKrylovSchur/BlockKrylovSchurEpetraExGenAmesos.cpp, BlockKrylovSchur/BlockKrylovSchurEpetraExGenAztecOO.cpp, and BlockKrylovSchur/BlockKrylovSchurEpetraExGenBelos.cpp.
