|virtual bool||applyShiftedMatrix (double alpha, double beta, const NOX::Epetra::Vector &input, NOX::Epetra::Vector &result) const =0|
|Call user routine for applying the shifted matrix where is the Jacobian matrix and is the mass matrix. |
Used by LOCA::Epetra::Group to provide a link to the external code for applying the shifted matrix in a matrix-free setting.
This interface is derived from the NOX::Epetra::Interface::Required and additionally provides a method for applying the shifted matrix . This is needed for linear stability analysis and Hopf tracking.
