A generalized Shift-HSS splitting method for nonsingular saddle point problems
In this paper, we propose a generalized shift-HSS (denoted by SFHSS) iteration method for solving nonsingular saddle point systems with nonsymmetric positive definite (1, 1)-block iphone 13 pro max price florida sub-matrix, and theoretically verify its convergence property.In addition, we discuss the algebraic properties of the resulted SFHSS preco
