解决时间序列的相关问题,本例是针对AR问题的建模代码。(Solutions for problems of time sequence analysis)

该matlab代码主要用于计算图像的边缘强度，信息熵，灰度均值，标准差(均方差MSE)，均方根误差，峰值信噪比（psnr），空间频率(sf)，图像清晰度，互信息(mi)，结构相似性(ssim)，交叉熵(cross entropy)，相对标准差。( calculate the uation average gradient, edge strength, information entropy, gray are Value, standard deviation (mean square error MSE), root mean square error, peak signal to noise ratio (psnr), spatial frequency (sf), image clarity, mutual information (mi), structure Similarity (ssim), cross-entropy (cross entropy), the relative standard deviation.)

using fast generated fuzzy c-means (fgfcm) for image segmentation.

说明：  一个多输入多输出小波网络的源程序，用matlab编写，能够实现对时间序列数据的训练预测(A multi-input multi-output wavelet network' s source code, written with matlab, can be achieved on the training time series data forecasting)

空时编解码程序，包括频偏信道模型（瑞利信道模型可选）(Space-time encoding and decoding procedures, including frequency offset channel model (Rayleigh channel models are available))

自己编写的小程序，产生任意阶数的m序列，希望对你有帮助(I have written a small program to generate arbitrary order m sequence, and you want to help)

说明：  介绍MATlAB的基本用法和编程技巧，是本学好MATLAB的优秀参考书。(MATlAB introduced the basic usage and programming skills, is an excellent reference book to learn MATLAB.)

声波传输损耗，有利于节约你的时间，希望广大爱好程序计算者喜欢 (acoustic transmission loss)

多维颜色直方图：：文中利用Matlab软件对真彩色图像高堆直方因数据的可视化进行了实践研究，并给出了 制作高雏直方图的相应程序。高雒直方图的可视化对真彩色图像分割中正确选择合适的彩色模型研 究起到了很好的作用。(multi-dimensional color histogram : : The authors use the Matlab software for true color images directly to the high rockfill for data visualization of practice, and given the high production of child histogram of the corresponding procedures. Luo high histogram visualization of the true color image segmentation correct choice of color model played a very good role.)
