| Abstract: | By applying the generalized singular value decomposition(GSVD) of matrix pairs and the properties of symmetric and skew-antisymmetric matrix,the expression of the symmetric and skewantisymmetric least square solutions of the matrix equation ATXA=C is given in this paper.In addition,according to the property of orthogonal matrix,the explicit expression of minimum norm solution is also derived in the corresponding symmetric and skew-antisymmetric solution set of the matrix equation. |
