还不错的程序 提取特征值的方式 需要的可以试试(the code for value)

简单的音乐合成实验，可以对以段现有的音乐进行傅里叶分析，并播放一段自己输入生成的音乐。针对信号系统Matlab应用的大作业编写(Simple music synthesis experiments, the section on Fourier analysis of existing music, and play a segment of the input generated by their music. Matlab application for a large signal system write operations)

并网型微网储能容量的优化，经济性分析。Horizon为总周期，单位为小时(Optimization of energy storage capacity and economic analysis)

说明：  利用小波分析具有时频局部化特性和熵能对系统状态进行表征的特点，将小波分析和熵结合起来，定义了3种小波熵（小波能谱熵、小波时间熵、小波奇异熵），并给出其算法，揭示了这3种小波熵对系统故障表征的机理，对两种理论信号和基于PSCAD/EMTDC仿真的输电线路故障信号(Based on the characteristics of time-frequency localization of wavelet analysis and entropy energy to represent system state, three kinds of wavelet entropy (wavelet energy spectrum entropy, wavelet time entropy and wavelet singular entropy) are defined by combining wavelet analysis and entropy, and their algorithms are given. The mechanism of these three kinds of wavelet entropy for system fault characterization is revealed. The results show that the three kinds of wavelet entropy can be used to characterize system fault Road fault signal)

有一学生成绩管理数据库如下表，要求建立一SAS数据集score，并输出显示 创建一个新的数据集class，新增平均成绩aver变量和等级考评grade变量，grade的值是根据aver值的大小给出A、B、C、D四个等级，并显示新数据集class(A student achievement management database as the table, called for the establishment of a SAS data set score, and output display create a new data set class, add an average score aver evaluation variables and grade level variables, grade values are based on the size of a aver value the A, B, C, D four grades, and displays the new data set of class)

说明：  这是一个陷波器的MATLAB代码，它可以滤除指定频率的干扰波！(trap filter 35 hz ，please download ！thank you very much！)
