本人长期从事matlab中simulink在无线通信上的仿真（通信抗干扰国家重点实验室），此Turbo迭代译码程序是我见过的最经典的链路，过程非常的清晰，尤其迭代译码部分巧妙的利用降速率用最简单的结构实现了复杂的迭代过程，值得同行学习，必有极大收获！(err)

说明：  matlab的边缘检测程序，里面还附带和别的算法比较程序(matlab edge detection process, which is also attached to the procedures and other algorithms)

（1） 自行设计产生两个离散序列信号，对其进行相加、乘及卷积运算。 （2） 利用filter命令求下面LTI系统的冲激响应： y(n)－0.7y(n－1)－0.6y(n－2) + y(n－3) = x(n) + 0.5x(n－1) （3） 画出系统的零极点图，判断系统的稳定性、因果性。 （4） 绘出系统的频响曲线。(lisan time signal analyse )

Three basic code PSO in Java and one in matlab, pdf files format, for english version ..you can use google translator

直流电机调速的matlab实现框图，方便易懂，值得参考。(Matlab block diagram of the DC motor speed control, easy to understand, it is also useful.)

说明：  一个LDPC的例程使用matlab编写，可直接运行，信道编码程序(a LDPC the use of Matlab routines prepared to be directly run channel coding procedures)

用matlab解线性规划,整数规划，非线性规划，混合规划以及其它的规划推荐使用YALMIP，它是matlab的工具箱.(Using matlab for solving linear programming, integer programming, nonlinear programming, mixed planning and other planning recommended YALMIP, it is the matlab toolbox. )

信号系统上机实验代码与指导书，采样、连续卷积、连续运算、连续系统(Machine experimental code and instructions on signal systems, sampling, continuous convolution, continuous operation, continuous system)
