摘要
利用广义奇异值理论和极值理论研究了非顺序主子阵约束下的双对称矩阵的一类约束矩阵方程问题及其最佳逼近,给出了解的表达式.
This paper mainly showed that the existence of and the expressions for the general solution of a kind of constrained matrix equation problem and the optimal approximation for biymmetric matrix under an unleaded principle submatrix, based on the generalized singular value decomposition and the minimum principle.
