How to delete workspace empty variables

Hello, I have a script that creates tons of variables in my workspace. However, some of them are worthless. For example, one will be a 3x1 cell array that is [ [] [] [] ]. How do I delete all these variables that are filled with empty cells?

note that, the variables arent empty themselves. Rather, they are cell arrays of certain dimensions filled with empty cells

Answer 1

[bio lim]

a=who; 
for var=1:length(a)
   b=eval([a{var}]);
   if isempty(b)
       eval(['clear ' a{var} ';'])
   end
end
clear a b

not working :/

[bio lim]

This should work assuming your variables are cell arrays.

c = cell(1,3); % Cell c and e are empty
d = cell(1,2);
e = cell(1,5);
d{1,1} = 4;
d{1,2} = 7;

 var = who;

 for var_num = 1 : length(var)
   if iscell(eval([var{var_num}])) 
     e = cellfun(@isempty, eval([var{var_num}]));
     h = true(size(eval([var{var_num}])));
     if isequal(h,e)
         eval(['clear ' var{var_num} ';'])
     end
   end
 end

 clear var var_num e h
 % Remaining variable is d
