【摘要】 本文首次利用布尔函数来研究 n 维2阶 Hadamard 矩阵,建立了它与 n 元 H-布尔函数之间的一一对应关系。从而使问题的研究得到了简化,在5维2阶 Hadamard矩阵的计数方面得到了一些新的结果。更多还原

【Abstract】 It is the first time in this paper to use the Boolean function to study n-dimen- sional Hadamard matrices of order 2.We established here the one to one correspondence between n-dimensional Hadamard matrices of order 2 and n-variable H-Boolean functions.And we obtained some interesting results of enumeration on the 5-dimensional Hadamard matrices of order 2.更多还原
