find( cellfun(@(C) numel(C) == 1 && C == 1, TEST) )
In the special case where each entry is only empty or a scalar, then
find( cellfun(@(C) C == 1, TEST) )
If you want to find a 1 anywhere in the cell:
find( cellfun(@(C) any(C == 1), TEST) )

TEST = {[1] [] [] [0] []} ;
% index position of 1
idx = find([TEST{:}] == 1)

If you switch to
TEST = {[0] [] [] [1] []} ;
then [TEST{:}] would be [0 1] and you would return an index of 2, but the actual index should be 4.
