Description: DQGMRES: a direct quasi-minimal residual algorithm based on incomplete orthogonalization. A truncated version of the GMRES method for solving large sparse systems of linear algebraic equations is presented. The authors propose the DQGMRES algorithm, which is based on the incomplete Arnoldi orthogonalization process and computes a sequence of approximate solutions with the quasi-minimal residual property. The new algorithm is studied theoretically and tested extensively on a number of numerical examples.
