平面波在介质中的传播，边界条件位pml。平面波在介质中的传播，边界条件位upml(Plane wave propagation in the medium, the boundary condition bit pml)

用matlab编程求解无约束优化问题、线性规划问题、非线性规划问题。(Programming using matlab for solving unconstrained optimization problems, linear programming, nonlinear programming problems.)

Ica的matlab算法，经过实验验证了，希望对大家有用(Ica the Matlab algorithms, after experimental verification in the hope that it may be useful to)

说明：  4. 试说明卷积编解码的工作原理。请用Simulink仿真卷积编码，并用Viterbi译码的方法进行解码，其中的编码、译码全部是自己编写代码(S-Function方式)，不是调用Simulink的已有编码、译码函数。请在加性白高斯噪声信道中，画出比特信噪比与误码率的关系曲线。(4 Explain the working principle of convolutional encoding and decoding. Please use the Simulink simulation convolutional coding and Viterbi decoding method used to decode, in which the encoding, decoding all write your own code (S-Function mode), instead of calling the Simulink existing encoding and decoding functions. In additive white Gaussian noise channel, signal to noise ratio and bit error rate to draw the curve.)

关于经过多径信道后，对于接收到的信息进行符号速率的估计，代码简洁易懂，有完整注释(After about multipath channel, the estimate for the received information symbol rate, the code is simple and easy to understand, complete comment)

说明：  研究智能算法的同学，可以参考这些例程学习(Students studying algorithms can refer to these routines)

基于元胞自动机模型对于交通事故下的高速公路交通流仿真，在不同大小车比例和交通流条件下，输出交通冲突数，评价道路是否安全。(Whether based on cellular automata model for highway traffic flow simulation in the accidents, the proportion of different sizes of vehicles and traffic flow conditions, the output number of traffic conflict,to evaluate of road safety.)

Write automatically written to a file using C + + code in order to make ns2 manual routing is used, used to set the node, which is our experimental multichannel implementation, hoping to share.

最小二乘回归分析算法，高斯白噪声的生成程序，有小波分析的盲信号处理。( Least-squares regression analysis algorithm, Gaussian white noise generator, There Wavelet Analysis Blind Signal Processing.)

说明：  三相逆变并网，采用全前馈能有效抑制谐振。(Three-phase inverters connected to grid can effectively suppress resonance by using full feed-forward.)
