Ifpack_OverlapFactorObject::Ifpack_OverlapFactorObject | ( | const Ifpack_OverlapGraph * | OverlapGraph | ) |
Constructor using Ifpack_OverlapGraph.
Creates an object from the overlap graph.
In | OverlapGraph - Graph describing the graph that should be used for the factors. |
Ifpack_OverlapFactorObject::Ifpack_OverlapFactorObject | ( | const Epetra_RowMatrix * | UserMatrix | ) |
Constructor using Epetra_RowMatrix.
Creates an Ifpack_Graph object from the user graph implicitly defined by the Epetra_RowMatrix interface.
In | RowMatrix - An object that has implemented the Epetra_RowMatrix interface. |
|
protectedpure virtual |
Virtual method that computes the factors as needed by the derived class.
This method is called by Factor() afer some safety checks have been performed.
Implemented in Ifpack_CrsIlut.
|
virtual |
Compute factors.
This function computes factors using the method DerivedFactor() that is implemented by the derived class. InitValues() must be called before the factorization can proceed.
|
virtual |
Initialize values from user matrix A, can be called repeatedly as matrix values change.
Processes matrix values, primarily handling overlap if any has been requested. This method then calls ProcessOverlapMatrix(), a virtual method that must be implemented by any class that derives from this class.
In | UserMatrix - User matrix to be processed. |
|
protectedpure virtual |
Virtual method that processes the overlap matrix as needed by the derived class.
This method is called by InitValues() afer the user matrix has been distributed to support overlap (if any overlap is requested). ProcessOverlapMatrix must be implemented by any derived class of Ifpack_OverlapFactorObject.
Implemented in Ifpack_CrsIlut.
