一种求解非对称线性方程组的JBICR算法
A JBICR Method for Solving Nonsymmetric Linear Systems
摘要
Abstract
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 Jacobibiconjugate 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.关键词
