这是一个求离散时间序列的功率谱的程序，是通过全波傅里叶变换来求的(This is a demand of the power spectrum of the discrete-time sequence program is through the full-wave Fourier transform to seek)

基本操作，主要是matlab的一些基本操作，适合初学者学习(Basic operations, mainly some of the basic operations of matlab for beginners to learn)

社交网络网络拓扑图，可以得出每个节点的连接关系(Social network network topology, you can draw the connection of each node)

说明：  基于MATLAB图像处理的应用及参考代码(MATLAB-based image processing applications and reference code)

说明：  一些关于iir滤波器设计的matlab实验代码(Some information about IIR filter design matlab code experiment)

说明：  仿真锁相环 及锁相环的MATLAB代码(pll MATLAB )

自己写的一个傅里叶变换程序，可以参考一下哦！~(A Fourier transform to write their own programs, you can refer to Oh! ~)

实现MATLAB下的音频AGC，，关键是要有高效的算法。效果不错。 (Audio AGC on MATLAB, the key is to have efficient algorithms. Good results.)
