"In mathematics, the generalized minimal residual method (GMRES) is an iterative method for the numerical solution of an indefinite 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 … See more Denote the Euclidean norm of any vector v by $${\displaystyle \ v\ }$$. Denote the (square) system of linear equations to be solved by $${\displaystyle Ax=b.\,}$$ The matrix A is … See more The Arnoldi iteration reduces to the Lanczos iteration for symmetric matrices. The corresponding Krylov subspace method is the minimal residual method (MinRes) of Paige … See more One part of the GMRES method is to find the vector $${\displaystyle y_{n}}$$ which minimizes $${\displaystyle \ {\tilde {H}}_{n}y_{n}-\beta e_{1}\ .\,}$$ Note that $${\displaystyle {\tilde {H}}_{n}}$$ is an (n + 1)-by-n … See more The nth iterate minimizes the residual in the Krylov subspace $${\displaystyle K_{n}}$$. Since every subspace is contained in the next subspace, the residual does not … See more Like other iterative methods, GMRES is usually combined with a preconditioning method in order to speed up convergence. The cost of the iterations grow as O(n ), where n is the iteration number. Therefore, the method is sometimes restarted after a number, say k, of … See more • Biconjugate gradient method See more • A.
