説明
A preconditioned method for saddle point problems is presented and analyzed. We directly generate an approximation of the inverse matrix, and apply the generated approximation as a preconditioner to some standard iterative solution methods. Moreover, we present a double preconditioned method for special saddle point problems. The method is illustrated by several examples derived from the surface fitting problems. Preliminary numerical results indicate that the method is efficient.
