摘要
提出了ｔ对称和（ｔ，ｔ１）对称矩阵．定义了ｔ对称（ｔ，ｔ１）对称和（ｔ，ｔ１）对称斜对称Ｈａｄａｍａｒｄ矩阵．给出了将任意Ｈａｄａｍａｒｄ矩阵变换为（ｔ、ｔ１）对称斜对称Ｈａｄａｍａｒｄ矩阵的三种等价变换．讨论了在上述意义下Ｈａｄａｍａｒｄ矩阵的若干性质．
t --symmetry and (t, t1) --symmetry matrix are presented. t --symmetry.(t. t1 ) --symmetry. (t1, t1 )--symmetry-- antisymmetry Hadamard matrix are definted.Moreover. three matrix equivalence transformations are given for transforming Hadamard matrix to (t. t1 ) --symmetry-- antisymmetry Hadamard matrix and some features of Hadanlard matrix under those above mentioned cases are discussed.
