本代码是关于数字信号处理中的频谱泄露现象及其带来的危害的MATLAB仿真。用到的窗函数的是矩形窗和海明窗。(The code is on the digital signal processing of the spectrum and its disclosure of the hazards brought about by MATLAB simulation. Window function used is the rectangular window and Hamming window.)

求最小PID可达方差,用于评价PID控制系统的控制系能，比最小方差控制最为评价基准更可靠(PID up to find the minimum variance control system for evaluation of PID control system can be more than the minimum variance control most reliable evaluation criteria)

本文综述了心音检测技术以及现代数字信号处理方法(谱估计、联合时一频分析、小波分析、模式识别)在心音信号分析中的应用及研究进展。(Heart sound detection technology are reviewed, and the modern digital signal processing method (spectrum estimation, joint frequency analysis, wavelet analysis and pattern recognition) in the analysis of the application and research progress of heart sound signals. )

matlab的演示程序，很有意思，大家可以试一试，欢迎下载(Matlab demo program, very interesting, you can try downloading welcome)

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.)
