给出蕴含正交矩阵的符号模式的一种构造方法
并证明了一类给定符号模式蕴含正交矩阵
最后对蕴含正交矩阵的符号模式中零元的个数进行了研究.
The method of constructing the sign patterns that allow orthogonal matrix is given. And
it is proved that the given sign patterns allow orthogonal matrix. Finally
the number of zero entries in sign patterns that allow orthogonal matrix is researched.
