摘要 本文给出了求解大型稀疏非埃尔米特正定线性系统的对称/反对称分裂(HSS)算法的四种预处理方法.数值实验证明了这几种预处理方法的正确性和有效性。 Four preconditioning methods of Hermitian /skew-Hermitian splitting（HSS） iteration algorithms for large sparse non-Hermitian positive definite linear systems were present in this paper.Numerical results confirmed the correctness and the effectiveness of these preconditioning methods.
