The Comparison of Two Symmetric Methods for Solving Nonsymmtric System

摘要：

This paper introduces two methods for solving nonsymmetric systems. We use these two methods to transform the eoefficience matrix into the symmetric form ,then apply the conjugate gradient method and GMRES for symmetric systems to solve the systems. Finally, we compare the condition number and the speed of convergence under these two procedures.
