三维fdtd的PML程序编写，少见的完全的版本(3D fdtd PML programmers, a rare complete version)

waveguide dispersion simulation

采用Simulink仿真工具，通过对二元对称信道的仿真，研究信道编码（如Turbo码等）对误码率的改善情况。(Simulink simulation tool used, through the binary symmetric channel simulation to study the channel coding (such as Turbo code, etc.) on the error rate to improve the situation.)

非线性混沌工具箱，可以用来求解非线性系统的分叉、混沌等(Non-linear chaotic toolbox can be used to solve the nonlinear system of bifurcation, chaos, etc.)

说明：  粒子群优化算法的基本思想是通过群体中个体之间的协作和信息共享来寻找最优解．(Particle swarm optimization algorithm based on the idea that groups of individuals through collaboration and information sharing to find the optimal solution.)

在DOA估计中，实际测量和理论肯定存在误差，比如通道误差，阵元位置误差，我们提出一种toplitz的预校正方法。(In the DOA estimate, the actual measurement and theory certainly exist errors, such as channel error, array (position errors, we put forward a kind of toplitz or calibration methods. )

很简单的入门资料，初学者必须学会的算法,希望好好看看(differental models)

粗糙惩罚算法，此算法能够分辨光谱数据中的坏点，并对坏点加以惩罚，即减小该点的权重值，从而使得数据更加真实平滑。(Roughness Penalty Smoothing)

说明：  潮流计算(matlab)

this is an open source and free code for calculation of E&B filed in presence of a current line.
