提出了一种求复逆正交矩阵参数化的新方法。这些矩阵是依赖于非零复参数的复Hadamard矩阵的自然推广。我们使用的方法是通过加倍逆复会议矩阵的大小。当自由参数在单位圆上取值时,逆正交矩阵变换为复Hadamard矩阵,从而得到了n= 8,10,12维Hadamard矩阵的新的参数化.
A novel method to obtain parametrizations of complex inverse orthogonal matrices is provided. These matrices are natural generalizations of complex Hadamard matrices which depend on non zero complex parameters. The method we use is via doubling the size of inverse complex conference matrices. When the free parameters take values on the unit circle the inverse orthogonal matrices transform into complex Hadamard matrices, and in this way we find new parametrizations of Hadamard matrices for dimensions n= 8,10,12.
