在matlab上运用有限时域差分法模拟二维光子晶体(the simulation of tm mode in two-dimensional photonic crystals using FDTD)

In mid-2003, someone in the Lounge asked for a list of time zones. I said that I had one, but the data was in a CodeBase/FoxBase file. Chris Maunder asked if I could retrieve that data and submit it to CodeProject. After procrastinating a few weeks, I decided to go ahead and not only extract the data, but to write a program to edit that data.

周武扬的编码理论，非常详细，包括汉明码、卷积码、差错控制编码等等。(the error code of zhou wu yang,very good,include hamming code,error chontrol code.)

this development will help to develop your program nicely. please read it and make improvement.

进一步采用基于距离和曲线形态的双尺度相似性度量谱聚类算法进行聚类处理，通过求n 个二次规划问题，就可以求得相似度矩阵W，降低了谱聚类算法对参数的敏感性，使算法更稳定(Furthermore, we use the two-scale similarity measure spectrum clustering algorithm based on distance and curve shape to carry out clustering. By finding n quadratic programming problems, we can obtain the similarity matrix W and reduce the sensitivity of the spectral clustering algorithm to the parameters Sex, make the algorithm more stable)

标准粒子群算法PSO,MATLAB中实验,对学习粒子群算法很有帮助(Standard particle swarm optimization PSO, MATLAB in experiments on learning PSO helpful)

这是关于matlab在解微分方程方面的应用，很实用。(This is about solving differential equations matlab in the application, it is practical.)
