摘要：
A new class of preconditioners based on the adaptive threshold incomplete multifrontal factorization for indefinite and complex symmetric systems is developed. Numerical experiments consisting of the 3D Helmholtz equations, fluid-structure interaction and localization problems demonstrate the excellent performance of the preconditioner.
