最大似然法德matlab仿真程序，用在ofdm系统中很好！！！与大家一起享用(Maximum Likelihood France and Germany Matlab simulation program used in ofdm system good! ! ! Together with everyone to enjoy!)

获取一个文件夹的创建时间、文件夹中文件内容及文件创建时间等信息(Get a folder was created, the contents of files in a folder and file creation time, etc.)

说明：  光谱特征波段的筛选，选择光谱数据中具有代表性的变量用以建立定量预测模型(This file is used to filter the spectral characteristic variables)

说明：  仿真一个瑞利衰落信道的信道冲激响应，横坐标是信道采样阶数，纵坐标是对应采样阶数的幅值.(Simulation of a Rayleigh fading channel the channel impulse response, the abscissa is the order of channel sampling, corresponding ordinate is the amplitude of the order of sampling.)

five set of data, and a specific value, the code give the closest value the given data and the idex

这个代码是直方图的一个应用，可以帮助了解直方图。(This code is an application of the histogram can help to understand the histogram.)

这个一个基于MATLAB的手写体数字识别的程序，非常的好用(The MATLAB-based handwritten numeral recognition procedure, very easy to use)

matlab原理图，很全很不错的的作业，是matlab入门必看等(Schematic matlab, matlab entry, etc.)

说明：  双层优化模型，求解思路是：首先对上层的决策变量编码，代人下层规划模型，通过求解下层模型的决策变量值，代入上层模型计算适应度值，然后进行交叉、变异、选择操作，最后求出最优解(two-layer optimization)

通过仿真实现同步电机模型，在MATLAB环境下实现(Achieve synchronous motor model by simulation in MATLAB environment to achieve)
