This paper, as a natural sequel to [1], gives the further consideration of problem I posed by Liao Anping and Guo Zhong in [2]: given X, Z ∈ Rn×m, Y, W ∈ Rn×l, find A ∈ R0n×n such that AX = Z, yTA = WT, where R0...
A criterion for the semipositive subdefiniteness of a 3× 3 block-matrix A is presented. applying the criterion, we give the general expression of left and right inverse eigenvalue problem of semipositive subdefinite ...
