Detailed Description

Interface to underlying groups for time dependent systems.

This abstract class provides an interface for time dependent problems, i.e., problems with a mass matrix (typically used in eignvalue or Hopf calculations). It provides pure virtual methods for computing and manipulating the shifted matrix $\alpha J + \beta M$ where $J$ is the Jacobian matrix and $M$ is the mass matrix.
