I've managed to break your efforts :-(

The problem is with these lines ...

      a = cellstr(num2str(a))
      S = cellstr(num2str(S))

The support for "rows" only works in the event that num2str() returns  
the same number of characters for each member of 'a' and 'S'

Here are *all* the tests in my local version (the last one fails).

%!assert (ismember ([1;2], 1:4), logical([1;1]));
%!assert (ismember ({''}, {'abc', 'def'}), false);
%!assert (ismember ('abc', {'abc', 'def'}), true);
%!assert (ismember (('abc')', {'abc', 'def'}), logical ([0; 0; 0]));
%!assert (isempty (ismember ([], [1, 2])), true);
%!assert (isempty (ismember ({}, {'a', 'b'})), true);
%!xtest assert (ismember ('', {'abc', 'def'}), false);
%!xtest fail ('ismember ([], {1, 2})', 'error:.*');
%!fail ('ismember ({[]}, {1, 2})', 'error:.*');
%!xtest fail ('ismember ({}, {1, 2})', 'error:.*');
%!assert (ismember ({'foo', 'bar'}, {'foobar'}), logical ([0, 0]))
%!assert (ismember ({'foo'}, {'foobar'}), false)
%!assert (ismember ({'bar'}, {'foobar'}), false)
%!assert (ismember ({'bar'}, {'foobar', 'bar'}), true)
%!assert (ismember ({'foo', 'bar'}, {'foobar', 'bar'}), logical ([0,  
1]))
%!assert (ismember ({'xfb', 'f', 'b'}, {'fb', 'b'}), logical ([0, 0,  
1]))
%!assert (ismember ("1", "0123456789."), true)
%!assert (ismember ("1.1", "0123456789."), logical ([1, 1, 1]))
%!assert (ismember([1:3; 4:6], [0:2; 1:3; 2:4; 3:5; 4:6], 'rows'),  
logical ([1; 1]))
%!assert (ismember([1.1,1.2,1.3; 2.1,2.2,2.3], [1.1,1.2,1.3;  
2.12,2.22,2.32], 'rows'), logical ([1; 0]))
