Detailed Description
template<class X, class Y>
class Dune::LinearOperator< X, Y >
A linear operator.
Abstract base class defining a linear operator , i.e.
and
hold. The simplest solvers just need the application
of the operator.
- enables on the fly computation through operator concept. If explicit representation of the operator is required use AssembledLinearOperator
- Some inverters may need an explicit formation of the operator as a matrix, e.g. BiCGStab, ILU, AMG, etc. In that case use the derived class
