Grouping variable must be a vector or a character array.

This is my code:
load classify_data
itr = 500;
hWaitBar = waitbar(0,'Image is still classifying...');
for i = 1:itr
data = train_feat;
groups = ismember(test_label,0);
[train,test] = crossvalind('HoldOut',groups);
svmStruct = svmtrain(data(train,:),groups(train),'showplot',false,'kernel_function','linear');
classes = svmclassify(svmStruct,data(test,:),'showplot',false);
end

All I can think of is that you might be generating only 0 or 1 train members, in which case groups(train) would be empty or a scalar.
