LFM信号的分数傅里叶变换分析，包含LFM信号分数阶谱图产生及FrFt子程序，及峰值搜索。非常好(LFM signal s fractional Fourier transform, including the LFM signal generation and FrFt fractional spectrum of subroutines, and peak search. Very easy to use.)

This code is used to cut selected part of the image that is of course after you decompress.   And run the code in the image circle separated.

matlab 学习技巧，现在把我用的，也就是对我帮助很大的留个文件传上去，希望对大家有用，第一入门与提高(matlab learning skills, and now I use, which is a great help to me to leave a document passed up, we want to be useful, the first entry and improve)

利用单纯形法求解，该方法简单易懂，有本人亲自编写，内容正确。(Use simplex method, the method is simple and easy to understand, has personally written content correctly.)

说明：  MATLAB在数字图像处理中，多次使用的语句，可以快速的学习数字图像处理(MATLAB in digital image processing, the repeated use of the statement, you can quickly learn digital image processing)

说明：  matlab的工具箱，拷贝到相关路径中便可以使用。非常全！(matlab toolbox, copy to the relevant path can be used. Very full!)

利用LSSVM的分类算法中多类分类算法程序，对企业的安全绩效实现评估。(using LSSVM classification algorithmmulti-class classification algorithm procedures to evaluate the security performance of a company )

基于光伏模块直流物理模型，在matlab 仿真环境下，开发了光伏阵列通用仿真模型。利用该 模型，可以模拟任意太阳辐射强度、环境温度、光伏模块参数、光伏阵列串并联方式组合下的光伏阵 列I-V 特性。此外，该模型还融合了光伏阵列的最大功率跟踪（MPPT）功能，可以用于光伏发电系统 和风光复合发电系统的动态仿真。(A Versatile simulation model for photovoltaic array is developed based on the DC physical model of photovoltaic module under Matlab environment. By the model，the I-V characteristics of photovoltaic array with different combinations can be simulated at any corresponding insolation level, ambient temperature and parameters of the photovoltaic module. In addition to that, the model includes the function of Maximum Power Point Tracking(MPPT) . It can be used in the dynamic simulation of photovoltaic systems and wind-solar hybrid systems.)
