Based on the properties of bisymmetric matrices, a class of constrained inverse eigenproblem and associated approximation problem for bisymmetric matrices were essentially decomposed into the same kind of subproblems for real symmetric matrices with small

摘要根据双对称矩阵的性质，将双对称矩阵的一类约束逆特征值问题及其逼近问题分解成具有较小阶数的实对称矩阵的同类子问题，然后利用实对称矩阵的结果导出双对称矩阵的这两个问题的解。
