An Approach to Making SPAI and PSAI Preconditioning Effective for Large Irregular Sparse Linear Systems
Zhongxiao Jia, Qian Zhang
We investigate the SPAI and PSAI preconditioning procedures and shed light on two important features of them: (i) For the large linear system with irregular sparse, i.e.…

Robust Dropping Criteria for F-norm Minimization Based Sparse Approximate Inverse Preconditioning
Zhongxiao Jia, Qian Zhang
Dropping tolerance criteria play a central role in Sparse Approximate Inverse preconditioning. Such criteria have received, however, little attention and have been treated heuristi…
