◆ apply()

template<class M , class X , class Y >
virtual void Dune::ILUSubdomainSolver< M, X, Y >::apply ( X &  v,
const Y &  d 
)
pure virtual

Apply the subdomain solver.

On entry v=? and d=b-A(x) (although this might not be computed in that way. On exit v contains the update

Implemented in Dune::ILU0SubdomainSolver< M, X, Y >.
