Detailed Description

An implementation of the solver interface using the SLEPc Krylov-Schur solver. Usage: All spectrum, all problem types, complex.

Constructor & Destructor Documentation

◆ SolverKrylovSchur()

SLEPcWrappers::SolverKrylovSchur::SolverKrylovSchur	(	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.
