WTMM中的一个很重要的m文件，给MATLAB用的(use for WTMM，an important part， for MATLAB)

这个程序就是最基本的粒子群优化算法程序，用Matlab实现，非常简单(This program is the most basic particle swarm optimization algorithm, using Matlab to achieve, is very simple)

SGA（Simple Genetic Algorithm）是一种强大的智能多变量优化算法，它模仿种群繁殖规律来进行 优化。(SGA (Simple Genetic Algorithm) is a powerful, intelligent multi-variable optimization algorithm, which imitate the laws of population reproduction is optimized.)

This LDPC software is intended as an introduction to LDPC codes computer based simulation. The pseudo-random irregular low density parity check matrix is based on Radford M. Neal’s programs collection, which can be found in [1]. While Neal’s collection is well documented, in my opinion, C source codes are still overwhelming, especially if you are not knowledgeable in C language. My software is written for MATLAB, which is more readable than C. You may also want to refer to another MATLAB based LDPC source codes in [2], which has different flavor of code-writing style (in fact Arun has error in his log-likelihood decoder).

采用fdtd方法，分别计算平面波照射到1维层介质的反射与透射以及在理想介质中的传播，场源可为高斯源或者正弦源，可以直观理解趋肤深度和边界概念(By fdtd method, were calculated to 1-dimensional plane wave radiation reflection and transmission media layer and spread in an ideal medium, the field for the Gaussian source or sources can be sinusoidal source, you can intuitively understand the concept of skin depth and the boundary)
