摘要: 借助四元数矩阵的复表示, 引进四元数矩阵范数, 研究四元数最小二乘 问题并得到了在四元数量子理论中解决四元数最小二乘问题的一种代数方法. 数值算例说明了算法的有效性.Abstract: This paper introduced concepts of norms of quaternion matrices by means of complex representation of a quaternion matrix, studied the quaternionic least squares (QLS) problem and derived an algebraic method of finding solutions of the QLS problem in quaternionic quantum theory. A numerical example verified the efficiency of the algorithm.
