THE INVERSE PROBLEM OF Ax=b IN THE CLASSES OF M-MATRICES AND S-MATRICES
Ax=b 在 M-阵和 S-阵类中的反问题

In this paper,the block criterion on M-matrix and S-matrix is given,the solvability con-ditions on the inverse problem of a system of linear equations Ax=b in the classes of M-matri-ces and S-matrices are discussed,and complete results are obtained.
