A fast implementationfor GMRES (Generalized Minimal Residual Algorithm) for solving a nonsymmetric system of linear equations.
The method approximates the solution by the vector in a Krylov subspace with minimal residual.

The Arnoldi iteration is used to find this vector. Instead of Givens rotation (which is more efficient) a QR decomposition is used (which is more clear).
