对于小样本而言，SVM的仿真效果要比神经网络好，但是SVM的性能依赖于它的两个训练参数，本算法是用GA自动选择SVM的两个参数。(For small sample case, SVM simulation results than the neural network is good, but the performance of SVM depends on its two training parameters, the algorithm is automatically selected GA parameters of SVM-2.)

说明：  学习使用matlab数学建模，包括了一些基本教程和经典的建模例子。(Learning to use matlab mathematical modeling, including some basic courses and classic modeling examples.)

关于神经网络的matlab程序，包括建立神经网络，仿真等···(Neural network matlab procedures, including the establishment of the neural network simulation)

自己写的几个小程序，包括冲激函数，阶跃函数，时域采样，恢复，内插等程序。很好用。(Write several small programs, including the impulse function, step function, time domain sampling, recovery, interpolation procedures. Good use.)

以一个dd.mat文件为例，编写如何在matlab中处理mat文件，得到其中的数据，虽然简单，但是很实用(Dd.mat file a case, write how to deal with mat files in matlab to get the data, although simple, but very practical)

本源代码用来进行虹膜区域检测，可以用来进行视线跟踪、眼睛区域检测等。(Iris source code used for detection, can be used for eye tracking, eye region detection.)

在科研中，大量时间花在统计年鉴的搜集上，例如找《中国城市统计年鉴》中2000多个市，要对分散的八个城市群找对应的数据，如果每次筛选会花费大量时间，如果做好excel表头，把对应的城市写上去会在多个文件多个工作组查找满足要求的数据，直接按需要保存成excel，进行后续分析。(In the research, the amount of time spent on the Statistical Yearbook of the collection, for example, to find " China City Statistical Yearbook" in more than 2000 cities and want to find a group of eight cities scattered corresponding data, if each screening will spend a lot of time, If you do excel header, the corresponding write up the city will look to meet the requirements of data in multiple files multiple workgroups, saved directly as needed to excel, for subsequent analysis.)
