Detailed Description

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 $\alpha J + \beta M$. This is needed for linear stability analysis and Hopf tracking.
