摘要：

In this paper, we consider least-square solutions of inverse problem for Hermitian generalized Hamiltonian matrices and their optimal approximation. We obtain a general expression of the least-square solution by using the singular value decomposition method. For any n x n complex matrix, we derive the representation of its unique optimal approximation in the least-square solutions set. (C) 2004 Elsevier Ltd. All rights reserved.
