模拟光束在二维三维介质中传输，用FDTD法，Matlab语言编写(beam simulation in 2D and 3D transmission medium, using the FDTD method, Matlab)

对光限制因子逐渐变大的波导进行光传输仿真(Simulation of the light transmission optical waveguide limiting factor becomes larger)

eof分解用的函数，说明如下：function [EOF,PC,F,diff]=EOFcgx(X) EOF分解。Xm*n 空间数据维数m，n为时间采样点 返回值EOF为空间模态,PC为时间模态。第一空间模态EOF(:,1),第一时间模态PC(1,:) 返回值F为特征值，diff为误差 (eof decomposition function as follows: function [EOF, PC, F, diff] = EOFcgx (X) EOF decomposition. Xm* n spatial dimension m, n is the time of sampling points Returns the value EOF spatial modes, PC is the time modes. The first space modal EOF (:, 1), the first time the modal PC (1, :) Return value F for eigenvalues, diff for error )

说明：  首先介绍一下早期的简单模型，即Boid（Bird-oid）模型。这个模型是为了模拟鸟群的行为而设计的，它也是粒子群优化算法的直接来源。(Because the simulation is too simple and far away from the real situation, a random variable is added to the velocity term, that is, in each iteration step, in addition to meeting the "nearest neighbor velocity matching", a random variable is added to each step of the speed, so that the whole simulation looks more realistic.)
