说明：  基于MATLAB的异步电机矢量控制，非常有用(Vector control of asynchronous motor based on MATLAB, very useful)

核主元分析程序，利用核函数将非线性数据映射到线性空间，再利用主元分析提取特征数据。(KPCA procedure uses the kernel nonlinear data mapped into linear space, and then using principal component analysis to extract feature data.)

文件中为几类贝塞尔函数，基于MATLAB编写(Bessel functions of several files, based on MATLAB prepared)

说明：  信息论学科中，费诺编码，香农编码，以及霍夫曼编码是三个最为重要的编码方式，改文件包含三种编码的Matlab程序。(In the discipline of information theory, Feyno coding, Shannon coding, and Hoffman coding are the three most important coding methods, and the change file contains three kinds of coding MATLAB programs.)

通常matlab不能进行整数规划，现一款混合整数的线形规划matlab m文件(Matlab usually can not be integer programming, are a mixed-integer linear programming matlab m file)

基于蒙特卡罗方法的试卷难度分布研究,Monte Carlo method based on the difficulty of distribution of papers(Monte Carlo method based on the difficulty of distribution of papers)

利用非线性控制完成光伏并网逆变器的设计，设计中采用模糊控制和反步法，介绍很好。(Using nonlinear control to complete the design of the photovoltaic (pv) grid inverter, adopted in the design of advanced reverse moves, the introduction is very good.)

说明：  二分法，牛顿法，黄金分割法的matlab实现。(Dichotomy, Newton method, the golden section method matlab implementation.)

高通滤波器的matlab实现具体源代码，数字图像处理处理中最常用的高频提取方法。(High-pass filter matlab source code to achieve specific, processing of digital image processing to extract the most commonly used method of high frequency.)

The NCT includes 4 External validity indices and 8 internal validity indices, and the sub-routine validity_Index.m is designed to use them. This tool is suitable for the research work such as the performance comparison of different indices on estimation of the number of clusters, algorithm design by improving part codes of this toolbox. i) External validity indices when true class labels are known: Rand index Adjusted Rand index Mirkin index Hubert index ii) Internal validity indices when true class labels are unknown: Silhouette Davies-Bouldin Calinski-Harabasz Krzanowski-Lai Hartigan weighted inter- to intra-cluster ratio Homogeneity Separation iii) Others Error rate (compared with true labels) System Evolution: it is used to estimate the number of clusters and give separable degrees between clusters.
