摘      要：In this paper,we are interested in HSS preconditioners for saddle point lin- ear systems with a nonzero(2,2)-th *** study an approximation of the spectra of HSS preconditioned matrices and use these results to illustrate and explain the spectra obtained from numerical examples,where the previous spectral analysis of HSS precon- ditioned matrices does not cover.
