PCA,KPCA完整程序，对研究人脸识别非常有用(this the code of pca and kpca)

本程序特别适合于弹道计算等方面使用。比ODE45函数的速度加快了很多，且程序充分展示了Matlab向量运算的强大功能，以及编程的简单快捷。(This procedure is particularly suitable for use ballistic calculations and other aspects. ODE45 faster than a lot of functions and procedures for demonstrating the power of Matlab vector operations, and programming simple and quick.)

gui filter it is usefull for matlab app

自己做的数字均衡器,包含GUI 界面，希望对大家有帮助。(digital equalizer)

说明：  信号功率谱的AR模型估的MATLAB代码( PowerSpectrum Density Estimation based on AR mode. and MATLAB file )

本程序给出了通信体制中十分重要的chirp信号（即线性调频信号）的产生方法，希望能对大家有一定的用处(This procedure gives a very important communication system chirp signal (ie, linear FM signal) is produced, and I hope we can have some useful)

维纳滤波器和一般滤波器的设计以及信号通过滤波之后的比较(Wiener filter and the general filter design and the comparison signal after filtering)

code for ofdm, good for study

对信号进行短时傅里叶变换，可以方便的调节各种短时傅里叶变换的影响因素。(Short-time Fourier transform of the signal, you can easily adjust a variety of short-time Fourier transform of the influencing factors.)
