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 >.
