Detailed Description

Epetra_LAPACK: The Epetra LAPACK Wrapper Class.

The Epetra_LAPACK class is a wrapper that encapsulates LAPACK (Linear
Algebra Package). LAPACK provides portable, high- performance
implementations of linear, eigen, SVD, etc solvers.

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

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

C++ includes: Epetra_LAPACK.h
