As we can see from the below code we have divided the data into four varaibles.now my question is how to divide the data into four variables having first dimension same like idxTrain and traindata should have first dimension same and idxtest and test data should have first dimension same.
Thank you.
cv = cvpartition(2310, 'KFold', 10);
idxTrain = training(cv, 1);
idxTest = test(cv, 1);
traindata = data(idxTrain, :);
testdata = data(idxTest, :);
