matlab约简算法,基于粗糙集信息系统约简的算法matlab实现

data2.txt的内容

decision2的内容

Matlab实现函数如下

f unction y=my_test() %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%读取信息系统文件

f ile = textread('data2.txt','%s','delimiter','\n','whitespace','');

[m,n]=size(f ile);

f or i=1:m

words=strread(f ile{i},'%s','delimiter',' ');

words=words';

X{i}=words;

end

X=X';

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%读取决策系统文件f ile = textread('decision2.txt','%s','delimiter','\n','whitespace','');

[m,n]=size(f ile);

f or i=1:m

words=strread(f ile{i},'%s','delimiter',' ');

words=words';

D{i}=words;

end

D=D'; %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
