A flexible global restarted GMRES for solving Sylvester equation(FGLGMRES-R)

In this paper, the global restarted GMRES method with right preconditioning and flexible preconditioning for solving Sylvester matrix equation are introduced. It is observed that the global restarted GMRES method with flexible preconditioning is more efficient and robust than the other methods. At the end of paper, the numerical example shows this efficiency.
