偏微分方程的波动方程数值解法,可选多个解法，对比作图(wave equation numerical solution)

一种基于小波的边缘检测算法，用matlab实现，程序有点长，希望耐心的阅读(Based on wavelet edge detection algorithm, using matlab to achieve, the program a bit longer, hoping patiently reading)

对matlab中的robotics toolbox中的函数功能及作用进行详细解说，方便初学者掌握函数。(Robotics toolbox for matlab in the function and role function in the detailed explanations, easy for beginners to master functions. )

说明：  快速反卷积。计算速度很快，必要的时候需要手动更改m文件里的fft点数以改变计算精度。很好的代码。(Rapid deconvolution. Computing speed very quickly, when necessary to manually change the m file points to change the fft calculation accuracy. Very good code.)

The DSI method is basically a modified SLM method. The additional aspect of the DSI method is to add M-bits dummy sequences to the original sequence in order to reduce the PAPR. Where, the dummy bits are inserted at the end of the data sequence (y). Next, after IFFT, we select the M-DSI sequence having the lowest PAPR.

给出接收信号眼图及系统仿真误码率，快速扩展随机生成树算法，有PMUSIC 校正前和校正后的比较。( The received signal is given eye and BER simulation systems, Rapid expansion of random spanning tree algorithm, A relatively before correction and after correction PMUSIC.)

考虑到通信网络结点的可靠性，若要求任意一个结点出现故障时，其它结点间仍然能够保持通信畅通的可能性都达到90 ，请建立问题的数学模型，设计求解算法，并给出使总铺设费用最少的铺设方案(Considering the reliability of communication network nodes, if you want any one node fails, you can still keep communication flowing between the possibility of other nodes are reached 90 , please build a mathematical model of the problem, the design algorithm, and give up some laying scheme of total laying cost at least)
