程序提取了很多直方图所需要的参数特征，如均值、方差、偏度、峰度、能量和熵。-chip_histogram_features

本程序使用matlab实现提取了很多直方图所需要的参数特征，如均值、方差、偏度、峰度、能量和熵。-This procedure used to achieve extracted a lot of matlab histogram parameters needed features, such as the mean, variance, skewness, kurtosis, energy and entropy.

基于大量数据二维图绘制程序。本例是对利用荧光光谱仪测得的茶叶数据进行二维图的绘制以便提取数据特征点。-Based on large amounts of data two-dimensional diagram drawing program. In this case tea data measured using the fluorescence spectrometer two-dimensional map of the draw in order to extract the data

kPCA程序，输入相应的参数后，可以直接运行，能应用到图像的特征提取与去噪等方面-kPCA program input parameters can be run directly, can be applied to image feature extraction and denoising

故障分为很多种，该程序是利用小波包把故障特征提取出来，用于判断接下来出现的情况是把一种故障-The fault is divided into many, the program is using wavelet packet to extract the fault features out, used to judge the next case to a fault
