#define HYPRE_ENUMS

EpetraExt_HypreIJMatrix: A class for constructing and using real-valued sparse compressed row matrices.

The EpetraExt_HypreIJMatrix is a wrapper class for Hypre parallel IJ matrices. It is derived from the Epetra_BasicRowMatrix class, and so provides Hypre users access to Trilinos solvers. This class is lightweight, i.e., there are no deep copies of matrix data. Whenever possible, class methods utilize callbacks to native Hypre functions.
