Constructor & Destructor Documentation

SLEPcWrappers::SolverGeneralizedDavidson::SolverGeneralizedDavidson	(	SolverControl &	cn,
		const MPI_Comm &	mpi_communicator = PETSC_COMM_SELF,
		const AdditionalData &	data = AdditionalData()
	)

SLEPc solvers will want to have an MPI communicator context over which computations are parallelized. By default, this carries the same behaviour has the PETScWrappers, but you can change that.
