| Abstract: | We presented a generalized Uzawa iterative method for solving the generalized saddle point problems based on the positive definite and skew Hermitian splitting (PSS) iterative method, that is, the modified local PSS iterative method, and analyzed the convergence of the method. Numerical results are illustrated to show that the effectiveness of the new algorithm. |
