Unrecognized variable name 'rows'

S = dataset('xlsfile','nss.xlsx') h = randperm(size(S,1)) g = S(h(1:2300),:) l = ismember(S,g,'rows') S(l<0.5, :) where nss.xlsx is a spambase dataset. but i am getting an error like "Error using getvarindices (line 25) Unrecognized variable name 'rows'.

Error in dataset/ismember (line 34) avars = getvarindices(a,vars,false);

Error in trainandtestseparation (line 4) l = ismember(S,g,'rows')"

You are trying to use this with a dataset, which will call the ismember method of this class and not the base MATLAB ismember. The documentation for the dataset version can be found here: ismember, but in this case you can just omit the 3rd input:

l = ismember(S,g)

Edit: Just realized I spelled MATLAB wrong. Rectified that situation.
