摘要
利用Cauchy-Schwitz不等式给出两个非负矩阵A与BHadamard积的谱半径一组上界,并且与前人给出的结果进行比较,通过例子验证所得的估计结果在一定条件下更为精确.
The author found a new upper bound of p (A.B) which was the spectral radius of Hadamard product of two nonnegative matrices A and,B by using Cauchy-Schwitz inequality and compared the new type upper bound with the classical results. Finally, example is given to show that the bounds are better than the previous results.
