/*! \class Teuchos::LAPACK
    \brief The Templated LAPACK Wrapper Class.

    The Teuchos::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 Teuchos::LAPACK class provides C++ wrappers for the LAPACK
    kernels in order to insulate the rest of Teuchos from the details of C++ to Fortran
    translation.  A Teuchos::LAPACK object is essentially nothing, but allows access to 
    the LAPACK wrapper functions.

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

    \note 
	<ol>
	    	<li>These templates are specialized to use the Fortran LAPACK routines for
		scalar types \c float and \c double.
    
		<li>If Teuchos is configured with \c --enable-teuchos-std::complex then these templates
		are specialized for scalar types \c std::complex<float> and \c std::complex<double> also.

		<li>A short description is given for each method.  For more detailed documentation, see the
		LAPACK website (\c http://www.netlib.org/lapack/ ).
