@article{Nasabzadeh_2016, title={An improvement of H. Wang preconditioner for L-matrices}, volume={5}, url={https://sciencepubco.com/index.php/ijamr/article/view/5371}, DOI={10.14419/ijamr.v5i4.5371}, abstractNote={In this paper, we improve the preconditioner, that introduced by H. Wang et al [6]. The H. Wang preconditioner \(P\in R^{n\times n}\) has only one non-zero, non-diagonal element in \(P_{n1}\) or \(P_{1n}\) , when \(a_{1n}a_{n1}
e 0\) . But the new preconditioner has only one non-zero, non-diagonal element in Â \(P_{ij}\) or Â \(P_{ji}\) if \(a_{ij}a_{ji}
e 0\), so the H. Wang preconditioner is a spacial case of the new preconditioner for L-matrices. Also we present two models to construct a better \(I+S\) type preconditioner for the Â \(AOR\) iterative method. Convergence analysis are given, numerical results are presented which show the effectiveness of the new preconditioners.}, number={4}, journal={International Journal of Applied Mathematical Research}, author={Nasabzadeh, Hamideh}, year={2016}, month={Oct.}, pages={182–186} }
