一些matlab的简单程序，对于初学者很有帮助的，好好看看 (Matlab some simple procedures, useful for beginners, a good look at)

基于粗糙集的特征子集筛选的一种算法 ！！！(Based on rough set feature subset selection of an algorithm! ! !)

TFIDF计算方法详细解释，代码解释很多，也有帮助文档(TFIDF calculation method explained in detail, explain a lot of code, but also help documentation)

一个新设计的OTSU算法，使用方法如下：％ load clown ％ subplot(221) ％ imshow(X/max(X(:))) ％ title( Original , FontWeight , bold ) ％ for n = 2:4 ％ Iseg = otsu(X,n) ％ subplot(2,2,n), colormap(gray) ％ imshow(Iseg) ％ title([ n = int2str(n)], FontWeight , bold ) ％ end(OTSU design a new algorithm, using the method as follows: load clown subplot (221) imshow (X/max (X (:))) title (Original, FontWeight, bold) for n = 2:4 Iseg = otsu (X, n) subplot (2,2, n), colormap (gray) imshow (Iseg) title ([n = int2str (n)], FontWeight, bold) end)
