Lopsided CRI Iteration Method for a Class of Complex Symmetric Linear Systems
摘要: 基于实部与虚部组合(CRI)迭代方法,提出了一种不平衡CRI (LCRI)迭代方法,用于求解复对称半正定线性系统。理论上利用谱理论分析了LCRI方法的收敛性,并给出了拟最优参数的表达式,数值上进一步验证了新方法的高效性。
Abstract: Based on the combination of real and imaginary parts (CRI) iteration method, a lopsided CRI (LCRI) iteration method is proposed for solving complex symmetric positive semi-definite linear systems. By using the spectral theory, we not only analyze the convergence property of the LCRI method, but also obtain the quasi-optimal parameter expression. The efficiency of the new method is further verified numerically.
