matlab中的类标转换程序

%进行排序，针对类标数目
orig_labels = sort(unique(Y));
Y_new = Y;
new_labels = 1:length(orig_labels);

for i=1:length(orig_labels)
Y_new(find(Y==orig_labels(i)))=Inf;
Y_new(isinf(Y_new))=new_labels(i);
end

Y = Y_new;

for i=1:length(orig_labels)
Y_old(find(Y_hat==new_labels(i)))=Inf;
Y_old(isinf(Y_new))=orig_labels(i);
end
