Hi,
I am encountering a problem while trying to extract L and U factors from
ILU IFPACK preconditioner.
In my code I have a RCP pointer to an Ifpack_Preconditioner object that
is initialized using the Create method of an Ifpack object (with "ILU"
as preconditioner type argument).
"Ifpack Factory;
RCP<Ifpack_Preconditioner> Prec;
Prec = Teuchos::rcp( Factory.Create("ILU", &*B_rcp, OverlapLevel) );"
When I invoke the method L() on the Ifpack_Preconditioner object
"Epetra_CrsMatrix L_factor= Prec->L();"
I get this compiling error:
"error: ‘class Ifpack_Preconditioner’ has no member named ‘L’"
Could you please suggest me how to solve this problem?
Thank you,
Lucia Mirabella
