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.)

各种颜色空间介绍(Introduced a variety of color space)

matlab程序提取语音信号的基音频率、共振峰、能量、MFCC等特征参数。(The matlab program to extract the speech signal fundamental frequency, Gong Zhenfeng, energy, MFCC and other characteristic parameters.)

两个简单序列的褶积，是地球物理信号处理的简单基本程序(convolution of two alignments)

利用GNSS 进行高精度导航定位的前提是正确固定载波相位观测值的整周模糊度。由Galileo 系统的4 个载波观测值可以 形成诸多有良好特性的组合观测值,利用这些组合观测值,结合MCAR 方法,可以有效地确定整周模糊度。(The use of high-precision GNSS navigation and positioning the premise is correct carrier phase observations fixed integer ambiguity. May consist of four carriers observations Galileo system There are many good characteristics to form a combination of observations using a combination of these observations, combined with MCAR method can effectively determine the integer ambiguity.)

说明：  自适应滤波和仿真实验，有毕设的同学可以参考下(Adaptive filtering and simulation experiments, there is complete set up for students to refer to the following)

说明：  双层优化模型，求解思路是：首先对上层的决策变量编码，代人下层规划模型，通过求解下层模型的决策变量值，代入上层模型计算适应度值，然后进行交叉、变异、选择操作，最后求出最优解(two-layer optimization)

扩散方程的求解，可根据初边值条件解出该方程.(Diffusion equation, initial boundary value according to the equation solved.)
