| Research Abstract |
This research showed the usefulness of the preconditioned which guarantees high precision theoretically to many realistic problems. Moreover, I think that it is greatly useful for the analysis of a future saddle point problem that it has checked that it was far practical for it to be cautious of the main eigenvalue instead of general pretreatment theory to a complicated saddle point problem, and to choose the preconditioned matrix according to a problem.
