该程序是用matlab编写的一个adaboost算法，并给出了迭代次数、样本数量与错误率间的关系。(The program is written in a matlab adaboost algorithm, and gives the number of iterations, the sample size and the relationship between error rate.)

聚类算法，不是分类算法。分类算法是给一个数据，然后判断这个数据属于已分好的类中的具体哪一类。聚类算法是给一大堆原始数据，然后通过算法将其中具有相似特征的数据聚为一类。这里的k-means聚类，是事先给出原始数据所含的类数，然后将含有相似特征的数据聚为一个类中。所有资料中还是Andrew Ng介绍的明白。首先给出原始数据{x1,x2,...,xn}，这些数据没有被标记的。初始化k个随机数据u1,u2,...,uk。这些xn和uk都是向量。根据下面两个公式迭代就能求出最终所有的u,这些u就是最终所有类的中心位置。(Clustering algorithm, not a classification algorithm. Classification algorithm is to give a figure, and then determine the data belonging to a specific class of good which category. Clustering algorithm is to give a lot of raw data, and then through the algorithm which has similar characteristics data together as a class. Here k-means clustering, is given in advance the number of classes contained in the raw data, then the data contain similar characteristics together as a class. All information presented in or Andrew Ng understand. Firstly, raw data {x1, x2, ..., xn}, the data is not labeled. K random initialization data u1, u2, ..., uk. These are the vectors xn and uk. According to the following two formulas can be obtained final iteration all u, u is the ultimate all these classes the center position.)

说明：  有用的动态仿真技术，希望对学习控制理论和虚拟现实技术有用。(useful dynamic simulation technology, and I hope to learn from control theory and virtual reality technology useful.)

算法由于提供了一个预测值,相对来说有简化.第五种方法,也就是ode45所得的精度最高尺度到了1e-18...简直可怕!一般很少有工程问题是它不能够满足的了,能够看出,解的差别在本问题里已经很明显了. (algorithm providing a predictive value, a relatively simplified. Fifth, ode45 is the highest accuracy of a scale of e-18 ... is simply terrible! it seldom works that asked that is not able to meet it in the can see that the solution of differences in the issues it is already very clear.)
