removing some the elements in cell array

data_array =

  1×5 cell array

  Columns 1 through 9

    {5×1 cell}    {5×1 cell}    {5×1 cell}    {5×1 cell}    {5×1 cell}    

    data_array{1,1}

ans =

  5×1 cell array

    {'PG02'}
    {'PG02'}
    {'PG02'}
    {'PG02'}
    {'PG02'}

The other cell arrays are similiar form. I need to remove first 3 (or last 3) cell elements from each sub cell arrays ({5×1 cell}). Then, the results will be :

data_array =

  1×5 cell array

  Columns 1 through 9

    {2×1 cell}    {2×1 cell}    {2×1 cell}    {2×1 cell}    {2×1 cell}

    data_array{1,1}

ans =

  5×1 cell array

    {'PG02'}
    {'PG02'}

My Matlab version is R2019a.

for k = 1:nunel(data_array)
   data_array{k} = data_array{k}(4:5);
   %         or  = data_array{k}(4:end);
   % Or:
   % data_array{k}(1:3) = [];
end
