| Abstract: | This paper is concerned with the inverse problem for n-by-n generalized doubly stochastic matrices.The least-square solutions of n×n generalized doubly stochastic matrices are studied.In addition,the problem of using generalized doubly stochastic matrices to construct the optimal approximation to a given matrix is discussed,and the expression of the solution is provided.The algorithms and numerical examples are included. |
