A new note on spectra of optimal and superoptimal preconditioned matrices

摘要：

Recently, Cheng et al. Lin. Alg. Appl. 422 (2007): 482-485 proposed the spectral comparison of optimal preconditioner in Chan SIAM J. Sci. Statist. Comput. 9 (1988): 766-771 and superoptimal preconditioner in Tyrtyshnikov SIAM J. Matrix Anal. Appl. 13 (1992): 459-473). In this paper, based on the work of Cheng et al., we further compare the spectra of optimal and superoptimal preconditioned matrices.
