       * ## Stationary methods

       *    1. Jacobi method - \ref TNL::Solvers::Linear::Jacobi

       *    2. Successive-overrelaxation (SOR) method - \ref TNL::Solvers::Linear::SOR

       *

       * ## Krylov subspace methods

       *    1. Conjugate gradient (CG) method - \ref TNL::Solvers::Linear::CG

       *    2. Biconjugate gradient stabilised (BICGStab) method  - \ref TNL::Solvers::Linear::BICGStab

       *    3. Generalized minimal residual (GMRES) method - \ref TNL::Solvers::Linear::GMRES
