matlab 文件，用于学习m文件，解释m文件的编写及用法，及注意事项(matlab documentation, for learning m paper explaining the preparation of the document m and usage, and Cautions)

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.

包含matlab中上百例程序，其中有简单函数程序，图像处理程序等(100 cases of middle and upper contains matlab procedures, including procedures for simple functions, image processing procedures)

小波分析的一些应用,毕业论文时做的,现在已经不做这个了(wavelet analysis applications, Graduation do, now do this the)

该程序实现多特征自适应阈值算法，两个matlab文件，一个为函数，该函数求出信号的特征量值并通过梯度下降法训练出其初始阈值，另一个为主函数，调用该函数文件；该程序将4路信号，每一路信号的特征量值及其自适应阈值求出来，并一起画出图来。(The program features multi-adaptive threshold algorithm, two matlab files, one for the function,the function seek out characteristics value and initial threshold value of the signal by gradient descent , the other main function, called the function file the program seek out four signals , characteristics of each road and the adaptive threshold value,then draw them together on the map.)

说明：  用MATLAB编写的BP算法在函数逼近中的应用。(BP algorithm using MATLAB written application in function approximation.)

电动汽车燃料电池simulink仿真模型，用于电动汽车或者混合动力汽车的仿真模型(Simulink simulation model of the electric vehicles fuel cells for electric vehicle or hybrid vehicle simulation model)

It is about the modeling and the simulation of the D.C machines under the Matlab software into which the libraries Simulink and SimPowerSystems are integrated. These libraries contain blocks of modeling which allow indicates it, simulation, the implementation and the system monitoring of communication and processing of the signal. The objective thus is to study the operation of the various types of D.C machines.

短时傅里叶变换的实现代码，可根据自己的信号改变参数仍可实现STFT(The implementation code of STFT)
