Classes
struct	Tpetra::Details::Blas::Lib::GemmCanUseLib< ViewType1, ViewType2, ViewType3, CoefficientType, IndexType >
	For this set of template parameters, can we implement Gemm (see below) using any compliant BLAS library, not counting the memory spaces of the given Kokkos::View specializations? More...
struct	Tpetra::Details::Blas::Lib::Impl::Gemm< ScalarType >
	Wrapper for the above wrappers, templated on scalar type (the type of each entry in the matrices). More...

Namespaces
	Tpetra
	Namespace Tpetra contains the class and methods constituting the Tpetra library.
	Tpetra::Details
	Namespace for Tpetra implementation details.

Detailed Description

Wrappers for the BLAS library's implementation of _GEMM; implementation detail of Tpetra::MultiVector.

Warning

This file, and its contents, are an implementation detail of Tpetra::MultiVector. Either may disappear or change at any time.

The point of this file is to wrap the BLAS library's _GEMM calls, so that application code is not exposed to BLAS-related extern declarations.
