摘要
针对求解大型稀疏非对称线性方程组,研究了大规模稀疏线性方程组的预条件迭代求解算法.结合Krylov子空间方法和Jacobi迭代,给出了一个新的求解算法,即预处理雅可比-双共轭残量法(简称JBICR),同时给出了算法的收敛性分析.数值实验显示了算法的快速收敛性.
In this paper, the preconditioning iterative method of large sparse linear systems has been considered for large spare linear systems with unsymmetrical coefficient matrices. Combining Krylov subspace methods with Jacobi iteration, a new algorithm of the preconditioning Jaeobi- biconjngate residual algorithm （ JBICR , in brief） has been proposed. Meanwhile, the convergence analysis has been presented. The numerical experiments showed that the new algorithm exhibited fast convergence performance.
