Improvement of the minimal residual method for solving nonsymmetric linear systems
In this paper, the minimal residual (MRES) method for solving nonsymmetric equation systems was improved,the recurrence relation was deduced between the approximate solutions of the linear equation system Ax = b, and a more effective method was presented, which can reduce the operational count and the storage.
