F-矩阵的性质与Hadamard不等式等号成立的条件

The Properties of the F-matrix and the Conditions of F-matrix Hadamard Inequality When dat A=∏ n i-1 aii

研究了F-矩阵及相关矩阵类的性质,得到的主要结果是:F-矩阵的逆及Schur补是F-矩阵;F-矩阵Had-amard不等式等号成立的条件.

In this paper,the author investigates the properties of the matrix and proves that the inverse of matrix and Schur complement of matrix are matri,which will lead to the matrix structures about matrix hadamard inequality when dat A=∏ni-1aii.
