通过BP网络实现对非线性函数（正弦函数）的逼近。函数比较短，很简练。(Through the BP network for the nonlinear function (sine function) approximation. Function relatively short and very concise.)

用NLMS基于符号的LMS算法完成仿真，并比较结果，包括不同信道参数w，不同数据块长度L对其的影响。(With NLMS symbol-based LMS algorithm to complete the simulation, and compare the results, including different channel parameters w, different data block length L of its impact.)

说明：  Ds直扩系统的一个仿真，不错的，可以看看(Ds DSSS system, a simulation, good, take a look at)

to understand the Algorithm go to matlab help in page dct2 and idct2 to get the mathematical expression for M = N = 8, we can calculate the most of hard values and save it as LUTs to speed up the execution now compare our special 8X8 functions with the internal general functions use this code: A = int32(100*rand(8,8)) tic for i = 1 : 1000 IDCT_8X8(DCT_8X8(A)) end toc tic for i = 1 : 1000 idct2(dct2(A)) end toc i had built the general functions too, but with low speed (to understand the Algorithm go to matlab help in page dct2 and idct2 to get the mathematical expressionfor M = N = 8, we can calculate the most of hard values and save it as LUTs to speed up the executionnow compare our special 8X8 functions with the internal general functionsuse this code: A = int32 (100* rand (8,8)) tic for i = 1: 1000 IDCT_8X8 (DCT_8X8 (A)) end toc tic for i = 1: 1000 idct2 (dct2 (A)) end toc i had built the general functions too, but with low speed)

基于Matlab三维数据点三角剖分方法研究，关于matlab在重建中的应用研究，有参考价值(Based on Matlab 3 d data point triangulation method, some research on the application of Matlab in the reconstruction, have reference value )

频散方程的相速度和群速度曲线分析和绘制，带备注。(frequency dispersion)

说明：  在网络理论中，小世界网络是一类特殊的复杂网络结构，在这种网络中大部份的节点彼此并不相连，但绝大部份节点之间经过少数几步就可到达(small world model)
