无标度网络生成程序。改程序可生成无标度的复杂网络，且很好展示了无标度网络的生成机理，对于初学者帮助很大。(Scale-free network generation program. Reform program will generate a complex network of scale-free, and good scale-free networks show the generation mechanism of great help for beginners.)

说明：  本程序用于对相机的标定，通过程序可以运算出相机的参数。对初学者有一定帮助(The procedure used for camera calibration, through the program can calculate the camera parameters. Certainly be of help for beginners)

用simulink编的科斯塔斯环，希望能有帮助(Simulink compiled Costas ring, hoping to help)

利用MATLAB对直扩信号的产生进行了研究，并利用FFT实现频谱分析(Use MATLAB to generate DS signals have been studied, and the realization of the use of FFT spectrum analysis)

fdtd 计算二位电磁脉冲的源程序，脉冲为高斯脉冲

这是使用有限差分法计算quasi TE模的程序,需要先定义波导的参数(This is the use of finite difference method quasi-TE mode procedures, the need to first define the parameters of Waveguide)

魔方还原程序,主函数为Cube,采用CFOP，还原步骤为88步左右，底面十字未优化；采用留个3*3矩阵，前面为froo（数字3），后面为baa（数字-3），左面为leff（数字-2），右面为rigg（数字2），上面为upp（数字0），下面为doo（数字1），(Cube restore process, the main function of Cube, using CFOP, the reduction step is 88 steps or so, the bottom cross unoptimized adopt leave a 3* 3 matrix, in front of froo (figure 3), followed by the baa (figure-3), left the leff (digital-2), the right of rigg (figure 2), at the upp (number 0), following the doo (figure 1),)

随机产生二进制序列，进行128QAM调制，画出星座图，通过加性高斯白噪声的信道，再画星座图，并计算误比特率。(128QAM modulate with MATLAB)

现代通信原理作业。窄带调频和窄带调相的方法来进行窄带角调制，还有ssb，vsb和pm调制的代码。(Modern communication principle operation. Narrowband modulation and narrowband phase modulation for narrowband angle modulation)

基于点的matlab图像配准.提出一种基于小波系数的特征索引算法，实现了图像特征点对的快速搜索和两幅图像之间的匹配(Based on the point of matlab Image Registration. Presents a feature based on wavelet coefficients indexing algorithm to realize the image feature points on the fast search and matching between two images)
