2012年全国大学生数学建模竞赛题目--葡萄酒的评价。文件中包含葡萄酒成分数据（Excel文件）、各种数据统计处理的MATLAB函数（已封装好，直接调用），包括：数据预处理、灰色预测、灰色关联度、基于熵权法的模糊综合评价、主成分分析、系统聚类、多元线性回归等程序。(Wines Evaluation from the title of 2012 National Undergraduate Mathematical ModelingContest. The file includes many MATLAB codes about statistical analysis of data.For example: Principal component analysis Grey Relational Analysis Fuzzy Comprehensive Evaluation Based on Entropy Method System Clustering Grey Prediction Multiple linear regression and so on. We can call them directly.)

Line Matrix is line impedance matrix. load_power Matrix is P+jQ matrix of the loads. source matrix is the complex value of the harmonic sources and they considered as a harmonic current source for each harmonic frequency.

DBT, A Matlab and Octave toolbox for radar modelling, signal simulation and processing. Release 2.156

noisegen.m：生成白噪声并按照指定信噪比对语音进行加噪； add_noisem.m：使用输入的噪音按照指定信噪比对语音进加噪； SNR_singlech.m：输入纯净语音和加噪后的语音，计算其信噪比； my_add_noise.m：调用上述函数进行加噪操作；(noisegen.m: white noise generated by the specified signal to noise ratio of the speech plus noise add_noisem.m: use the specified input noise into the signal to noise ratio of the speech plus noise SNR_singlech.m: pure voice input and processing after the noise voice, calculate the signal to noise ratio my_add_noise.m: call the above functions plus noise operation )

利用matlab程序编写物理实验中的双缝干涉实验和牛顿环的实验，有助于老师进行数字教学(Using Matlab program to write the experiment of double slit interference and the experiment of Newton ring in physics experiment, it is helpful for teachers to carry on digital teaching)
