在 MATLAB Online 中打开

 n = size(data,1);
 data_rand = data(randperm(n),:);
 m = ceil(n/10);
k = 1:m:n-m;
test = data_rand(k:k+m-1,:);
train = [data_rand(1:k-1,:); data_rand(k+m:end,:)];
adj=edge(train,data);

i assume that dataset is k=[1 2;3 4;8 5;8 9;6 5] then train set is t=[1 2;3 4;6 5] and test set is the remaining i.e test=[8 5;8 9]

i want repeat this process 10 times with different choice but the same percentage
