Detailed Description

template<>
class Anasazi::MultiVecTraits< double, Epetra_MultiVector >

Template specialization of Anasazi::MultiVecTraits class using the Epetra_MultiVector class.

This interface will ensure that any Epetra_MultiVector will be accepted by the Anasazi templated solvers.

Note: The Epetra package performs double-precision arithmetic, so the use of Epetra with Anasazi will only provide a double-precision eigensolver.

Examples:: BlockDavidson/BlockDavidsonEpetraEx.cpp, BlockDavidson/BlockDavidsonEpetraExGen.cpp, BlockDavidson/BlockDavidsonEpetraExGenPrecIfpack.cpp, LOBPCGEpetra.cpp, LOBPCGEpetraEx.cpp, LOBPCGEpetraExGen.cpp, LOBPCGEpetraExGenPrecIfpack.cpp, and LOBPCGEpetraExSimple.cpp.
