| چکیده مقاله |
| In this paper, we propose a new projection method to solve large Sylvester matrix equations. The new approach projects the problem onto extended global Krylov subspace and gets a low dimensional equation. We use the global Golub-Kahan bidiag- onalization procedure to construct the F-orthonormal bases for the extended Krylov subspaces. Finally, we give some theoretical results and present numerical experiments. |
