AMDiS::LinearSolverInterface::finish
virtual void finish()=0
Cleanup the solver, e.g. free the previously created factorization.

Definition: LinearSolverInterface.hpp:8
AMDiS::LinearSolverInterface::init
virtual void init(M const &A)=0
Prepare the solve (and preconditioner), e.g. make a factorization of the matrix, or extract its diago...
