摘要
得到的一个矩阵乘积不等式及其逆向不等式.应用这些结果,把一个半正定矩阵Khatri-Rao乘积的不等式推广到实对称矩阵,并给出了它的逆向不等式及其等式条件.
We firstly obtain an inequality of matrices product and its converse inequality. Applying these results, the inequality of Khatri-Rao product about positive semi-definite matrices is generalized to real symmetric matrices, and its inverse inequality and equational condition are also given.
