说明：  2D光子晶体Y形结的数值模拟的matlab程序(2D photonic crystal Y-shaped junction of numerical simulation)

先建立lorenz吸引子，在分别做出X,Y,Z的时序图，最后用X重构向空间，在TAU取不同值时，图的效果也不一样(Lorenz X phase three-dimensional reconstruction of attractor figure)

this is a starting tool for gui in matlab

该算法为基于克隆选择原理的人工免疫算法。算法有三部分，第一部分为传统的遗传算法，第二部分CSA算法，两方法对一些函数求极值，可比较各自的特点。(The algorithm is based on the principle of artificial immune clonal selection algorithm. Algorithm has three parts, the first part of the traditional genetic algorithm, the second part of the CSA algorithm, two methods for some function extreme, can compare their characteristics.)

用Matlab实现的DES算法。在Matlab窗口输入DESDECP(a,b,n),其中a，b表示16进制的明文和密钥，n为1表示加密，否则表示加密。(DES algorithm using Matlab. In Matlab window field DESDECP (a, b, n), where a, b indicates a hexadecimal plaintext and key, n is 1 shows an encryption, or that encryption.)

说明：  内含8个数学建模的实验报告：线性规划、插值、拟合、非线性规划、蒙特卡洛方法、微分方程、无约束优化、回归分析(Mathematical modeling includes 8 Experiment Report: linear programming, interpolation, fitting, linear programming, Monte Carlo method, differential equations, unconstrained optimization, regression analysis)
