| 摘 要： | 讨论了子矩阵约束下三类矩阵方程的对称正交对称迭代解,利用广义共轭梯度法构造了迭代算法,并证明了算法的有限终止性.该算法能自动判定解的情况:当矩阵方程(组)相容时,得到矩阵方程(组)的解;当矩阵方程(组)不相容时,得到矩阵方程(组)的最小二乘解.

| Abstract: | Iterative solutions of three kinds of matrix equations with sub-matrix restrains on symmetric ortho-symmetric matrix set are investigated,and iterative method by the generalized conjugate gradient method is constructed,and its limited termination is proved.The information of solutions can automatically be judged by this method.When the equation(equations) is consistent,the solutions of the equation(equations) can be obtained.When the equation(equations) is inconsistent,the least-squares solutions of the equ... |
