he modeling equation of this system is MD2X+bDX+kX = F The transfer function between the displacement X(s) and the input F(s) then becomes X(s) / F(s) = 1 / (Ms2 + bs +k)

用Matlab实现中值滤波与Otsu算法 包括彩色图转256灰度，灰度图中值滤波处理，再用Otsu算法处理。(Median filter implementation using Matlab and Otsu algorithms including 256-color map turn gray, grayscale median filter, and then Otsu algorithm processing.)

qdpsk调制主要是帮助那些需要代码的朋友们，这些代码仅作参考，如有疑问请留言！！！谢谢(qdpsk modulation is mainly to help friends who need the code, the code is only for reference, if any questions please leave a message! ! ! Thank you)

k means techniques de classification non supervisée (clustering) les plus utilisées. Etant donné un entier K, K-means partitionne les données en K groupes, ou "clusters", ou "classes" ne se chevauchant pas. Ce résultat est obtenu en positionnant K "prototypes", ou "centroï des" dans les régions de l espace les plus peuplées. Chaque observation est alors affectée au prototype le plus proche (règle dite "de la Distance Minimale"). Chaque classe contient donc les observations qui sont plus proches d un certain prototype que de tout autre prototype

matlab的学习资料，从最基础开始，逐步走进编程世界(Matlab learning materials, the most basic start, gradually into the programming world)

说明：  假如数据中有N 个变量，而我们想抽取的样本的数量是M,那么在对数据进行抽样的时候，这种方法首先会把N个变量的设计空间均匀的划分开为M份，然后在每个划分好的区域中随机的抽取一点，最后，从这M个变量里，随机挑选之前选好的点，构成我们的样本(If there are n variables in the data, and the number of samples we want to extract is m, then when sampling the data, this method will first divide the design space of n variables into M parts evenly, and then randomly extract a point in each divided area. Finally, from the m variables, randomly select the previously selected points to form our sample)
