实现霍夫曼编码，根据随机概率编程霍夫曼码，有详细解释。(Huffman coding to achieve, according to random probability programming Huffman code, a detailed explanation.)

here is a program MATLAB for maximum smallest, Tiệ m có thể

提出了一种多迸制频移键控(M娲K)信号调制分类及解调方法，选取截获接收机输出的MFSK信 号的时频脊线作为分类特征，利用无监督聚类算法求取最佳聚类数M．利用时频脊线的Ham：小波变换 估计码元宽度，并且利用对应最佳聚类数的聚类中心确定抽判门限，通过对时频脊线抽样判决，实现了 MFSK信号的解调．理论分析和对实际信号的处理结果证明了此算法的可行性．(new algorithm is proposed for elassillcation and demodulation of MFSK signals．The ridge of time— frequency representation of MFSK signals is analyzed．Modulation elassi_fieation is realized by using the unsupervised clustering algorithm to determine the optimal nulnllt2r of clusters．In order to demodulate MFSK signals，the Haar wavelet transform is used to estimate the code—width and the centers of optimal clusters are used to determine thresholds．Theoretical analysis and practical signal processing results justify the robusticity and the efficiency of the new classification and demodulation Mgorithm．)

使用非线性支撑矢量机对一组数据进行分类。画出分界面(The use of non-linear support vector machine classification on a set of data. To draw the interface)

电力电子系统建模与控制，经典教材之一，电力电子人的必备啊(Modeling and control of power electronic systems, one of the classic textbook, power electronics people essential ah)

异步电动机的矢量控制仿真，用simulink做的，里面还有一个讲解用的PPT。(Induction motor vector control simulation, simulink do, there is also a narrator with the PPT.)

it is used to improve the image quality

说明：  平滑滤波，自己写的小程序，希望对大家有所帮助(Filtering, write a small program, we want to help)

精通MATLAB7 王正林版配套源码，很值得学习(Proficient in MATLAB7 Zhenglin version supporting source, it is worth learning from)
