用K均值算法和C模糊算法对sonar数据和iris数据进行分类。 K均值算法是一种很常用的聚类算法，其基本思想是，通过迭代寻找K个聚类的一种划分方法，使得用这K个聚类的均值来代表各类样本是所得到的的总体误差最小。 模糊C均值（FCM）算法在K均值算法的基础上，用模糊子集代替确定子集，从而得到模糊的分类结果，即分类结果的模糊化。(Sonar data and iris data are classified by means of K mean algorithm and C fuzzy algorithm. The K mean algorithm is a very common clustering algorithm. Its basic idea is to find a partition method of K clustering by iteration, so that the average error of the mean of the K clustering is minimized. The fuzzy C mean (FCM) algorithm is based on the K mean algorithm. The fuzzy subset is replaced by the fuzzy subset, thus the fuzzy classification result is obtained, that is, the classification result is fuzzed.)

G-P算法计算关联维的 Matlab 程序 (升级版，mex函数，超快) ----------------------------------- 更新部分： 引入限制短暂分离参数，使该参数大于序列平均周期时，去除了同一轨道前后点的关联， 使 r 值较小时，ln r - ln C(r) 曲线接近线性(G-P method to calculate the correlation dimension of the Matlab program (upgrade version Files function, Ultrafast)----------------------------------- Update parts : the introduction of restrictions on temporary separation parameters so that the parameter is greater than the average cycle sequence, In addition to the same orbit around the point and makes a relatively small r, r ln- ln C (r) almost linear curve)
