Examples
- In the forth part , the paper uses markowtiz mean - variance analysis in portfolio choice and capital markets and professor zhang zhongzhen pivoting operation to solve portfolio loans
第四部分，文章利用markowtiz的资产选择理论和张忠桢教授的枢轴旋转运算法试图解决贷款组合问题。 - This paper first discusses how to use the simple transformation to realize the process of image rotation and gives its cost , then points out that the rotation of 2d image can be realized with three translation operations through decomposing matrix , and finally gives the possibility and superiority for using quaternions to substitute matrix in 3d space
本文先讨论用简单变换实现图像旋转的过程和代价，并指出通过矩阵分解可以将二维旋转运算简化为三次一维的平移运算，最后给出3d空间中使用四元数替换矩阵的可能性和优越性。
