Detailed Description

The solvers in ISTL do not work on matrices directly. Instead we use an abstract operator concept. This allows for using matrix-free operators, i.e. operators that are not stored as matrices in any form. Thus our solver algorithms can easily be turned into matrix-free solvers just by plugging in matrix-free representations of linear operators and preconditioners.
