[Trilinos-Users] Can Ifpack generate all its types of preconditioners for Epetra_Crs and Epetra_FECrs matrices ??

[Williams, Alan B]

If Ifpack accepts Epetra_RowMatrix objects, then it should accept Epetra_FECrsMatrix object. This is because Epetra_FECrsMatrix has Epetra_CrsMatrix as a base class, which in turn has Epetra_RowMatrix as a base class. Thus, Epetra_FECrsMatrix "is a" Epetra_RowMatrix.

Hi

I am new to Ifpack.

I see that Ifpack accepts (in most cases) Epetra_RowMatrix objects.
Can Ifpack generate all its types of preconditioners  for Epetra_Crs and
Epetra_FECrs matrices ??
Can I convert my Epetra_FE_Crs or Epetra_Crs matrices so that they could be
feed into Ifpack as
Epetra_RowMatrix objects ??
Please Comment
