这个系统是基于matlab的双闭环直流调速系统，控制器使用了单片机，性能达到了设计要求。(The system is based on the matlab dual closed loop DC system, the controller uses single chip, the performance meets the design requirements.)

基本粒子群优化算法Matlab源程序 主要用于对PSO的基本理解与思考 (Particle swarm optimization algorithm Matlab source)

基于matlab源码的通信技术及方法描述，有大量实例(Matlab source code-based communication technologies and methods described, a large number of examples)

很好的matlab书籍！供大家学习参考。请同行批评指正！上传更好更高质量的文章。程序和源代码！(Matlab good books! Reference for them to learn. Peer criticism please! From the article, higher quality better. Procedures and source code!)

KMEANSK Performs K-means clustering given a list of feature vectors and k The argument k indicates the number of clusters you want the data to be divided into. data_vecs (N*R) is the set of R dimensional feature vectors for N data points. Each row in data_vecs gives the R dimensional vector for a single data point. Each column in data_vecs refers to values for a particular feature vector for all the N data points. The output data_idxs is a N*1 vector of integers telling which cluster number a particular data point belongs to. It also outputs centroids which is a k*R matrix, where each rows gives the vector for the cluster center. If we want to segment a color image i into 5 clusters using spacial and color information, we can use this function as follows:

在小波去噪中，采用循环平移不变量去噪法，可以抑制Pseudo-Gibbs现象。(Wavelet de-noising, using cyclic shift invariant denoising method can suppress Pseudo-Gibbs phenomenon.)

K-S，即kolmogorov检验法，亦称拟合优度检验法。用来检验给定的一组数据是否来自分布F=F0，原理是若H0成立，则max|v/n-F0(qj)|应该很小，用手算几乎在绝大多数情况下是不可能的，通常借助统计软件，如SAS，S+等(K-S, namely Kolmogorov test, also known as goodness of fit test. It is used to test whether a given set of data comes from the distribution F=F0, and the principle is that if the H0 is set up, the max|v/n-F0 (QJ) should be very small, and the hand calculation is almost impossible in most cases, usually with the aid of statistical software, such as SAS, S+, etc.)
