Hello all,
Let's say I have a basic cell array : x = {1 2 3 4 5 8}. Now, I want to verify that this array only contains those numbers and if not return an error message.
Like so:
if x ~= 1 | 2 | 3 | 4 | 5 | 8
disp('error');
end
How would I make this work? Please note that it needs to remain a cell array.
Thank you

If I understand correctly, this will work
if not(all(ismember(cell2mat(x),[1 2 3 4 5 8])))
disp('error');
end
