In this paper, the generalized anti-reflexive solution for matrix equations (BX = C , XD = E), which arise in left and right inverse eigenpairs problem, is considered. With the special properties of generalized anti-reflexive matrices, the necessary and sufficient conditions for the solvability and a general expression of the solution are obtained. Furthermore, the related optimal approximation...

By the proposed iterative algorithm, the least Frobenius norm reflexive solution of the matrix equation can be d...
