脑电分析ＭＡＴＬＡＢ工具，由国外脑电研究实验室开发，很实用(EEG analysis)

是Grey Method的使用方法，方便好用，欢迎大家下载，如果有问题，也欢迎给我留言，我的QQ号码是：55101(Gray Method is the way to use of convenient and you are welcome to download, if there are problems, I also welcome to voice mail, my QQ number is : 55101)

本程序中得到的收端OFDM信号的频谱波形，是与其发端信号的排步有关的。在发端的 ％ 载波安排上，128个载波有前后各32个载波是null载波(如果这前后各32各载波是带外频段， ％ 那么理论上它们都应该是零！)，中间的64个载波是数据载波。这样的排步很明显就是一个 ％ 两边低，中间高的频谱形式。所以，收端也应该是这个轮廓。 (this process the resumption end of the spectrum OFDM signal waveform, with the originator of the signal further on the row. The originator% carrier arrangements, 128 of the carrier after a 32 carrier is null carrier (if it was around the 32 is the carrier frequency band. % then theoretically they should be zero!) the middle 64 carrier data carrier. This arrangement is obviously further 1% lower on both sides, in the middle of the spectrum form high. Therefore, the admission should end this profile.)

广义神经网络在预测中有广泛的应用，参数设置简单，值得学习。(Generalized neural network is widely used in the forecast, the parameter setting is simple, it is worth learning.)

说明：  用matlab实现利用统计混沌方法解决非线性系统时间序列预测的问题(achieved using Matlab using statistical methods to solve nonlinear chaotic time series forecasting system problems)

1.将BMP图像内容读入内存数组。 2. 调整图像的灰度，对图像进行灰度变换（反变换）。 3. 对图像进行较正,分别取值为0.4,0.6,0.8.(1. The BMP image content is read into memory array. 2 Adjust the gray image, the image gray-scale transformation (inverse transform). 3 more positive image, respectively, the value of 0.4,0.6,0.8.)

Simple imlementation of hamming code (7,4) The genearator matrix is given by Reference of book Error Correction coding Mathematical models and alogrithms Chapter 1, Hamming Codes code is hamming code (7,4)

GSCALE Scales the intensity of the input image. G = GSCALE(F, full8 ) scales the intensities of F to the full 8-bit intensity range [0, 255]. This is the default if there is only one input argument. G = GSCALE(F, full16 ) scales the intensities of F to the full 16-bit intensity range [0, 65535]. G = GSCALE(F, minmax , LOW, HIGH) scales the intensities of F to the range [LOW, HIGH]. These values must be provided, and they must be in the range [0, 1], independently of the class of the input. GSCALE performs any necessary scaling. If the input is of class double, and its values are not in the range [0, 1], then GSCALE scales it to this range before processing. The class of the output is the same as the class of the input.
