# EPSARNOLDI

EPSARNOLDI = “arnoldi” - A basic Krylov method for non-Hermitian problems, with explicit restart.

## Notes

This solver is very basic and is not recommended in general, since it will not be competitive with respect to other solvers.

The implemented method is Arnoldi with explicit restart and deflation. Generally, it is much better to use implicit restart as in `EPSKRYLOVSCHUR`.
