DGMRES.h file
DGMRES solver for (generally) non-symmetric linear systems.
This header provides the DGMRES (Deflated GMRES) solver class, an iterative method for solving linear systems:
for general (possibly non-symmetric) matrices.
DGMRES accelerates restarted GMRES by deflating (approximations of) invariant subspaces associated with slow-to-converge eigencomponents.
Notes
- This implementation uses Eigen's unsupported DGMRES.
Usage Example
Solver::DGMRES solver(problem); solver.setTolerance(1e-10).setMaxIterations(1000).setRestart(50).solve();
