Ax＝b在广义正定矩阵类中的反问题

The Inverse Problem of Ax=b in the Class of Generalized Positive Definite Matrices

研究线性方程组Ａｘ＝ｂ的反问题在广义正定矩阵类中的求解，得到了一个简便的充要条件。

The necessary and sufficient conditions for the solution of the inverse problem of a system of linear equations, Ax=b , in the class of generalized positive definite matrices, are presented. The main results obtained are given and so the inverse problem of Ax=b is more completely solved.
