I understand that 'tabulate' will give the list of variable names and their frequencies.
https://www.mathworks.com/help/stats/tabulate.html#:~:text=tabulate(%20x%20)%20displays%20a%20frequency,as%20a%20cell%20array%20otherwise.
Its output is tb and its first element is the list of variables.
I can display tb(:,1) as a vector.
But when tb(:,1) has many elements, displaying them as vectors will take a lots of spaces and also cannot see the list of all variables in one display. Then, how can one has something in a concise way like
tb(:,1)={Hawaii, Washington, California, New Mexico,...}
?

The output of tb(: , 1) is a cell array with all the variables. You can run this script. It will store the result in a res variable which is a vector
res = [];
cell = tb(:, 1);
for i = 1 : numel(cell)
res = [res cell{i}];
end

If tb(: , 1) is a cell array then it should work. Can you share the output of tb(: , 1) ?
