fft

matlab系统仿真的说明，例子多样清楚，简单易懂(system simulation matlab note, for example, clearly diverse, easy-to-read)

PSO的matlab源程序，根据所要解决的目标函数不同而另外再编辑一个适应度函数文件，然后用此MATLAB文件调用就可以了(pso in matlab)

PCA原代码，可以移植到别的pca算法中使用，具有较强的可移植性。(PCA original code can be transferred to other pca algorithm used, with a strong portability.)

ECG on reposo test taken on 250 Hz (sampling frequency) You can use in order to obtain (and compare) the stress (from HRV)

实现四路复用程序。通过walsh正交码的复用技术，matlab仿真(achieve multiplexing process. Walsh orthogonal codes through the Reuse, Matlab simulation)

image compression algorithm

说明：  二阶巴特沃斯(Butterworth)低通滤波器(Low pass filter)

能够进行信号的Hilbert-Huang变换的matlab语言代码，使用的是以前的老算法计算的，但是已经证明可用，希望能对初学者有帮助(Used to implement the input signal of the Hilbert-Huang transform. First proposed calculation method, after validation, can be used.Based on Matlab.)

EMD的程序要用到matlab的时频工具箱 matlab的工具箱的安装步骤： 1.解压下载的文件包，将tft/mfile复制到matlab的toolbox文件夹下 2.建立搜索路径，matlab->file->Set Path->Add Folder ->选择mfile文件夹复制到matlab的toolbox的路径->save->close 3.测试是否建立搜索路径成功，在matlab命令窗口打入：which fmsin 返回的结果是你放mfile的正确路径说明建立搜索路径成功。此时就完成了安装工具包的工作。(EMD program to use when the frequency of matlab toolbox matlab toolbox installation steps: Unzip the downloaded file package, copy tft/mfile to the toolbox matlab file folder 2 established the search path, matlab-> file-> Set Path-> Add Folder -> Select mfile folder to the toolbox matlab path-> save-> close 3 test whether to establish a successful search path in matlab command window enter: which fmsin The result returned is the correct path you put mfile instructions to establish a successful search path. This time to complete the installation kit work.)
