这是2009年huang在EMD基础上改进的算法EEMD的matlab代码！(the matlab code for EEMD！)

对cdma系统进行仿真，包括误码率统计等，结果输出到result.dat文件当中。(simcdma.m allows a set of CDMA parameters to be simulated, such as BER verse number of users, etc. All the graphs used in the thesis were generated using this script. The output from this script is a Result.txt file which is a comma delimited spread sheet compatible file.)

说明：  该程序在MATLAB环境下编译，用于重构一维时间序列的相空间轨迹，并找出最佳的重构延迟步长或时间。(The program compiled in MATLAB environment for the reconstruction of time series of one-dimensional phase space trajectory, and the Reconstruction of the best step length or time delay.)

说明：  几个matlab解常微分方程的例子：验证齐次方程有形如1/(xM+yN)的积分因子；全微分方程；求方程的显式解和绘图；解出x的隐方程的解法；方程的隐式解(Several examples of matlab Ordinary Differential Equations: Homogeneous Equation physical verification, such as 1/(xM+ yN) of the integral factor the whole equation the explicit solution of Equation and drawings solve the implicit equation x Solution equation the implicit solution)

实数编码的小生境PSO算法优化多模态函数(Real-coded niche PSO algorithm for multimodal function optimization)

说明：  包括一些常用算法及MATLAB实现，如可视化仿真。 (Visual simulation code)

这是一个对于频率选择性瑞丽信道的仿真，希望对大家有所帮助(This is a Ruili for frequency-selective channel simulation, we hope to help)

基于2-D DFT-DWT的小波变换，绝对可以执行，只需要按程序的更改相应图片名字即可(2-D DFT-DWT of the image edge extraction procedure )

对于初学者具有参考意义，具有丰富的参数选项,IDW距离反比加权方法。( For beginners with a reference value, It has a wealth of parameter options, IDW inverse distance weighting method.)

:详细介绍了基于LabV IEW和Matlab的虚拟信号分析仪的设计过程。该信号分析仪可以完全替代传统意义上的信号分析仪,实现其全部功能,并且具有造价低(只在通用计算机上增加一块数据采集卡) ,使用方便,可实现资源共享,更新换代容易等特点。(: Details LabV IEW and Matlab-based virtual signal analyzer of the design process. The signal analyzer can completely replace the traditional sense of the signal analyzer to achieve its full functionality, and has low cost (only in a general increase in computer data acquisition card), easy to use, can realize the sharing of resources, such as upgrading easy characteristics.)
