灰度共生矩阵提取图像纹理特征，采用matlab实现，包括模糊c均值实现分类(Gray-level co-occurrence matrix texture features extracted images using matlab realize, including the realization of fuzzy c-means classification)

说明：  找一幅曝光不足的灰度（或彩色图像），按照直方图均衡化方法进行处理(Underexposed to find a gray (or color image), according to the method of histogram equalization processing)

一本关于龚纯编辑的数学建模MATLAB应用的书，很实用的，不过不是很清晰(Gong edited a book on mathematical modeling of pure MATLAB application book, very practical, but not very clear)

Wireless Communication Principles and Practice (Second Edition). The famous Rapport full book that provides the details of all the wireless communication techniques.

时频分析工具，自编的小程序，可以进行fft变换，和一些信号分析。(time-frequency analysis tool, designed a small procedure can be carried out fft transform, and some signal analysis.)

说明：  随机切换系统稳定性和利用matlab线性矩阵不等式工具箱求可行解(Stability of stochastic switched systems using MATLAB LMI toolbox to find feasible solutions)
