| چکیده | ||
| The Lyapunov matrix equations occur in many branches of control theory, such as stability analysis and optimal control. In this work, we introduce a novel iterative approach to address the generalized Lyapunov matrix equation within the framework of complex matrices. The procedure involves solving two conventional Lyapunov equations with real-valued coefficient matrices at each iteration. The scheme incorporates two positive parameters, for which we establish sufficient conditions to guarantee the convergence of the method under certain assumptions. Then we solve the Lyapunov equation arising from applying a finite difference procedure to the Helmholtz equation by the proposed method. | ||
