穿墙传播带来的误差分析例程，对于非视距的认识可以加深(error analysis about through-wall propagation)

此程序采用FDTD方法编写，可以用来观察和验证电磁波的绕射(This program is written using the FDTD method can be used to observe and verify the electromagnetic wave diffraction)

说明：  防碰撞时隙ALOHA的matlab仿真算法(The matlab slot ALOHA anti-collision simulation algorithm)

说明：  该文件包括几篇比较关于LDPC编码核心的基础读物，还有关于LDPC开发的MATLAB仿真库和运用该库所进行的一些仿真源码(The documents include a few more LDPC coding on the basis of the core reading, also on the development of the LDPC MATLAB simulation library and use the library for the simulation source code)

以化学中反映扩散问题的Brusselator模型为例，采用MATLAB对大型Stiff问题进行仿真求解。(Reflected in the chemical diffusion problems Brusselator model as an example, using MATLAB simulation of large Stiff problem solving.)

This GUI can be used to regulate any controllable, nonlinear system to the origin.* It uses a switched Lyapunov control function. The nonlinear system can be of any order and with any number of inputs. There are some beta options as well, including adaptation. The beta features have not been well-tested nor mathematically proven but they can be useful in practice.
