初等旋转方阵的推广

Generalization of Elementary Rotating Square

由n维向量b的坐标求出所需的初等旋转方阵的推广形式.方阵中有2~k阶主子方阵为文献[1]中特殊方阵B的几种形式;此方阵左乘b^T可使b中2~k-1个元素化为0.当k=1、2、3时,此方阵可以是正交的,其中k=1的方阵正是初等旋转方阵.

The generalized form of the elementary rotation square is obtained by the coordinate of n-dimensional vector b. This square is master phalanx in ref. [1] for several types of special square B; The square left multiplication bTcan make the b-1 to 0. When k = 1,2,3,the square can be orthogonal,the k = 1 square is elementary rotated phalanx.
