光栅的矩阵传输MATLAB程序，是用来求折射率周期分布的光栅的反射率和折射率的(MATLAB program grating transfer matrix is ​ ​ used to find the grating period distribution of the refractive index and refractive index of the reflectance)

简要阐述了遗传算法的基本原理,探讨了在MATLAB 环境中实现遗传算法各算子的编程方法, 并以一个简单的实例说明所编程序在函数全局寻优中的应用。(Briefly describes the basic principles of genetic algorithms discussed in the MATLAB environment to achieve each operator genetic algorithm programming methods, and a simple example illustrates the functions programmed in the application of global optimization.)

将Iris数据集分为2组，每组各75个样本，每组中每种花各有25个样本。其中一组作为以上程序的训练样本，另外一组作为检验样本。为了方便训练，将3类花分别编号为1，2，3 。 　　使用这些数据训练一个4输入（分别对应4个特征），3输出（分别对应该样本属于某一品种的可能性大小）的前向网络。(The Iris data set is divided into two groups each of 75 samples in each group have 25 samples in each flower. One set of sample programs as more training, another group as the test samples. To facilitate training, the three types of flowers were numbered 1,2,3. Training before using these data a 4-input (respectively 4 features), 3 outputs (respectively the possibility should belong to a variety of sample size) to the network.)
