MATLAB: Manipolation of cell array and

cellcell arraysforfor loop

I have three cell array as per below and I would like to create a for loop that read directly one per time the three array and do the sum of the numeric value (columns 3 and for) for each groups. Is it possible?
Groups{1}
    Groups{2}
    Groups{3}
ans = 
      'a'    'b'    [1]    [2]    [3]
      'a'    'b'    [3]    [4]    [5]
ans = 
      'b'    'z'    [3]    [4]    [5]
      'b'    'z'    [4]    [5]    [6]
ans = 
      'r'    't'    [5]    [6]    [7]
      'r'    't'    [6]    [7]    [8]

Best Answer

Do you want to sum the 3rd and 4th column all together or separately? Anyway, it should be similar to this.
Out=zeros(size(Groups));
for k=1:numel(Groups)
  Out(k)=sum([Groups{k}{:,3}]);
end
