摘　　要：利用矩阵的奇异值分解和矩阵对的商奇异值分解,讨论了子矩阵约束下反对称正交反对称矩阵的反问题,给出了其有解的充分必要条件及在有解条件下的通解表达式,并得到了此问题的最佳逼近解,给出了求最佳逼近解的数值算法及数值算例,验证了方法的有效性.By applying the singular value decomposition and the quotient singular value decomposition, the inverse problem of anti-bisymmetric anti-orth-bisymmetric matrices with a sub-matrix constraint was studied firstly. Second, the sufficient and necessary conditions and the general solutions of the problem are provided and the optimal approximate solution is given. Finally, numeral algorithm and example are given to show the effectiveness of the proposed method.
