Abstract: | For the given matrices of A∈C t × m,B∈Ct×n,C∈Cp×m,D∈Cn×q,E∈Cp×q,this paper provides the necessary and suffi-cient conditions and expression for generalized reflexive solutions by using singular-value decomposition and generalized singular-value decomposition.Based on it,the expression of the optimal approximation is derived. |
