Detailed Description

Amesos_TestRowMatrix: a class to test Epetra_RowMatrix based codes.

Class Amesos_TestRowMatrix enables the creation of a Epetra_RowMatrix derived class for testing purposed. This class requires another Epetra_RowMatrix as input, and minimic the behavior of this matrix. However, as it this object is not derived from Epetra_CrsMatrix or Epetra_VbrMatrix, a dynamic_cast will not result in any Epetra_CrsMatrix or Epetra_VrbMatrix object.
