程序设计步骤：
1、去均值
2、计算协方差矩阵及其特征值和特征向量
3、计算协方差矩阵的特征值大于阈值的个数
4、降序排列特征值
5、去掉较小的特征值
6、去掉较大的特征值(一般没有这一步）
7、合并选择的特征值
8、选择相应的特征值和特征向量
9、计算白化矩阵
10、提取主分量(Programming steps: 1 to mean 2, calculation of covariance matrix and its eigenvalues and eigenvectors 3, the calculation of covariance matrix eigenvalues greater than the threshold number of 4, in descending order of eigenvalue 5, remove the smaller eigenvalue 6, remove the larger eigenvalue (usually not this step) 7, the combined choice of eigenvalues 8, select the appropriate eigenvalues and eigenvectors 9, computing whitening matrix 10, principal component extraction)

题目：取一个整数a从右端开始的4～7位。
程序分析：可以这样考虑：
(1)先使a右移4位。
(2)设置一个低4位全为1,其余全为0的数。可用~(~0<<4)
(3)将上面二者进行&运算。
2.程序源代码：(Topic: take an integer a from the right end of the four to seven began.
Program analysis: it can be to consider:
(1) to make a move to the right four.
(2) sets a low four total for the 1, all the rest for 0 of the number. Can be used to (~ 0 < < 4)
(3) will above the difference and operations.
2. The source code:)
