Detailed Description

Ifpack_Graph_Epetra_RowMatrix: a class to define Ifpack_Graph as a light-weight conversion of Epetra_RowMatrix's.

Class Ifpack_Graph_Epetra_RowMatrix enables the construction of an Ifpack_Graph based on the input Epetra_RowMatrix. Note that data are not copied to this object; instead, wrappers are furnished.
