Constructor & Destructor Documentation

SolverJacobiDavidson()

SLEPcWrappers::SolverJacobiDavidson::SolverJacobiDavidson	(	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 as the PETScWrappers, but you can change that.
