/* External definitions of the Superlu functions
 *
 * Note that we do include the "slu_*defs.h" files provided for each
 * data-type.  This produces linker warnings, but keeps us from
 * including SuperLU code in our own code (even if only extern
 * declarations, which would eliminate linker warnings).  This is
 * because there are several declarations (as of SuperLU 4.1) across
 * these headers which conflict with each other in C linkage.  All of
 * the conflicting functions, on the other hand, we do not care about.

   * \brief Pass function calls to Superlu based on data type.
   *
   * Helper class which passes on function calls to the appropriate
   * Superlu function based on the type of its scalar template argument.
   *
   * Superlu has solver and matrix builder functions defined based on
   * data type.  One function for complex, one for double precision
   * complex, another for \c float , and yet another for \c double.  To
   * work elegantly with the Amesos2::Superlu interface we want to be
   * able to perform a single function call which is appropriate for the
   * scalar type of the Matrix and MultiVectors that we are working
   * with.  The \c FunctionMap class provides that capability.
   *
   * The class template is specialized for each data type that Superlu
   * supports.  The Amesos2::create function assures that an
   * unspecialized FunctionMap will never be called by the solver
   * interface.
   *
   * Please see the <a
   * href="http://crd.lbl.gov/~xiaoye/SuperLU/superlu_ug.pdf">Superlu Users'
   * Guide</a> for more information on the TPL functions.
