利用Tikhonov正则化实现的超分辨率图像序列的重建，效果还好(Use Tikhonov regularization to achieve super-resolution image sequence reconstruction, better results)

利用matlab仿真雷达直射波与地面反射波干涉的雷达方向图。（仰角的大小对雷达作用距离的大小的影响）(Using matlab simulation radar direct wave direction of reflection wave interference with the ground radar chart. (the size of the size of the elevation of the radar range))

和Huffman-Tree一样，Shannon-Fano coding也是用一棵二叉树对字符进行编码。但在实际操作中呢，Shannon-Fano却没有大用处，这是由于它与Huffman coding相比，编码效率较低的结果（或者说香农-范诺算法的编码平均码字较大）。(And Huffman-Tree, like, Shannon-Fano coding is using a binary character coding. However, in practice it, Shannon-Fano, but not much use, since it is compared with the Huffman coding, coding efficiency is the result of a lower (or Shannon- Fano coding algorithm larger average code word).)

均匀线阵因子方向图，可以修改为不同参数下的方向图，是以极坐标的图形显示。(ULA factor direction map, can be modified for different parameters under the direction of maps, based on polar coordinates of the graphical display.)

使用matlab做的离散时间单位冲激响应(Discrete-time unit impulse response)

自己编写的55行精短情诗代码，呈现红色背景、白窗心形图案及动态U型符号，释义“Need you !”，码农也能文艺！(55 lines fine short poems codes, showing heart-shaped background and dynamic symbol-U,meaning "Need you!")

The proposed approach satisfies the integrability condition and does not need any boundary condition assumptio-ns, we have designed a stand-alone, flexible Matlab implementation that enables to evaluation the proposed approach. The experiments on real images show the approaches ability to reconstruction the surface from SFS.

动态规划算法的顺序（前向求最小值）算法的matlab实现以及一个算例，还有一篇参考pdf文献，适合初学者，有我个人的一点注释(Dynamic programming algorithm for the sequence (prior to seeking the minimum value) algorithm matlab to achieve, as well as a numerical example, there is a reference pdf document, suitable for beginners, there are my personal notes that)

说明：  几种通信信号的调制识别matlab程序，希望对研究者有帮助(Modulation Recognition of Communication Signals of several matlab program, the researchers hope to help)

输入齿轮基本参数，绘制数字齿轮图形，并生成离散齿轮数据点坐标。(The basic parameters of the input gear, illustrated with digital gear graphics, and generate the coordinates of the discrete gear data points.)
