sbs和sfs特征提取的MatLAB源代码用于多维向量提取最优(sbs Feature Extraction)

说明：  matlab拥有很强的计算功能，里面有很多指令需要会用。(failed to translate)

随机矩阵为小波变换的压缩传感，包含有系数采样、随机矩阵、重构算法程序(compressive sensing)

OFDM系统中，发送机的仿真程序，可以运行，已经很好的在本机上运行了，是分析OFDM系统的好的开始(OFDM system, the transmitter of the emulator, you can run, have a good run on this machine is a good start OFDM system analysis)

这几个程序是我用matlab做图像分割用到的，方法是四叉树分解，大家可以参考下(These programs do I use matlab image segmentation used, the method is the quadtree decomposition, we can refer to)

将Pedro F. Felzenszwalb的 Efficient Graph Based Image segmentation 作者提供的c代码封装，提供了Matlab调用接口。 输入参数如英文所示。(offer the matlab code interface of pedro F. Felzenszwalb s efficient graph based image segmentation （image,sigma 0.8,k 300,min_size 100) )

随机森林指的是利用多棵树对样本进行训练并预测的一种分类器，包括两个方面：数据的随机性选取，以及待选特征的随机选取。(Random forest refers to the use of more than one tree to sample the training and prediction of a classifier, including two aspects: random selection of data, as well as the characteristics of random selection.)

matlab的经典案例，小程序，适用于初学matlab的同学(matlab classic cases for student who are learning matlab)
