四元数自共轭矩阵的一个性质

A property of quaternion self-conjugate matrix

讨论了四元数自共轭矩阵的一个性质,利用该性质把n阶四元数正定(半正定、负定)自共轭矩阵的定义予以简化,得到了与四元数自共轭矩阵的相同结论.

A property of quaternion self-conjugate matrix was discussed. The definition of n order quatemion positive definite （positive semi-definite, negative definite）self-conjugate matrix was simplified using this property and the same conclusions with quaternion self-conjugate matrix were drawn.
