Detailed Description

Epetra_BLAS: The Epetra BLAS Wrapper Class.

The Epetra_BLAS class is a wrapper that encapsulates the BLAS (Basic
Linear Algebra Subprograms). The BLAS provide portable, high-
performance implementations of kernels such as dense vectoer
multiplication, dot products, dense matrix-vector multiplication and
dense matrix-matrix multiplication.

The standard BLAS interface is Fortran-specific. Unfortunately, the
interface between C++ and Fortran is not standard across all computer
platforms. The Epetra_BLAS class provides C++ wrappers for the BLAS
kernels in order to insulate the rest of Epetra from the details of
C++ to Fortran translation. A Epetra_BLAS object is essentially
nothing, but allows access to the BLAS wrapper functions.

Epetra_BLAS is a serial interface only. This is appropriate since the
standard BLAS are only specified for serial execution (or shared
memory parallel).

C++ includes: Epetra_BLAS.h
