关于四元数矩阵弱直积与强圈积的不等式的一个注记

A Note About Inequalities of Weak Direct Products and Weak Circular Products of Quaternions Matrices

本文推广、改进了由伍俊良在文［１］中所得到的四元数矩阵弱直积与弱圈积的奇异信的一些不等式。

This paper generallzes and improves some inequalities of singular values for weak directproducts and weak circular preducts of quaternions matrices obtained by Wu Junliang in the peper[1]。
