使用Matlab 即可讀寫Excel檔案內容. 不要另外打開Excel 檔(Use Matlab to access contents of the Excel file. )

实现了parzen窗的方窗和高斯窗形式算法，输入只需输入样本，样本个数和窗宽能的出其概率密度函数(A window algorithm for Parzen windows)

说明：  VMD代码，该程序对信号进行经验模式分解，可以用于故障信号处理，还可以与很对方法结合。如，排列熵，emd,vmd,等，包含VMD、EMD、EEMD工具箱，可用于变分模态分解、EMD以及EEMD谐波检测对对比分析(VMD code, the program for empirical mode decomposition of signals, can be used for fault signal processing, can also be combined with a very good method. For example, permutation entropy, EMD, VMD, etc., including VMD, EMD, EEMD toolbox, can be used for comparative analysis of variational mode decomposition, EMD and EEMD harmonic detection pairs)

对OFDM系统的发送端和接受端信号的频谱进行仿真，还有星座图(On the OFDM system transmitter and the receiving end of the spectrum signal simulation, there are constellation)

用Newmark直接积分算法分析61杆桁架结构的动力学特性。(Conduct the dynamic response analysis for the 61 trusses structure by Newmark.)

Raptor结果分析，对实验结果的分析，各种不同类型的曲线描点(Raptor performance analyze)

This method handles the border by repeating the closest values to the point accessed. This is different from matlabs border handling.
