Detailed Description
template<class X>
class Dune::MINRESSolver< X >
class Dune::MINRESSolver< X >
Minimal Residual Method (MINRES)
Symmetrically Preconditioned MINRES as in A. Greenbaum, 'Iterative Methods for Solving Linear Systems', pp. 121 Iterative solver for symmetric indefinite operators. Note that in order to ensure the (symmetrically) preconditioned system to remain symmetric, the preconditioner has to be spd.
