MATLAB: Calculating percentage value and cancanating

matrix

I have values as 
gene =
      {6x3 cell}
      {6x4 cell}
      {5x5 cell}
      {4x6 cell}
      {3x6 cell}
      {2x6 cell}
In gene{1,1}
'Genes'        'T0&T2'  'T2&T4'  'T4&T6'
'YAR029W'  'd'  'd'  'd'
'YAR062W'  'du'  'ud'  'du'
'YAR068W'  'du'  'uu'  'uu'
'YBL095W'  'du'  'ud'  'du'
'YBL111C'  'uu'  'ud'  'du'
'YBL113C'  'uu'  'uu'  'ud'
i want to calculate percentage starting from 3rd row
result{1,1}
'Genes'        'T0&T2'  'T2&T4'  'T4&T6'   ''
'YAR029W'  'd'  'd'  'd'       ''  
'YAR062W'  'du'  'ud'  'du'      60
'YAR068W'  'du'  'uu'  'uu'      60
'YBL095W'  'du'  'ud'  'du'      60  
'YBL111C'  'uu'  'ud'  'du'      60
'YBL113C'  'uu'  'uu'  'ud'      60
percentage is calclated by (no of rows/5*100)=3/5*100
i tried 
emptycells = cell2mat(cellfun(@(x) ~isempty(x),gene,'uni',0));
 perempty = sum(emptycells(2:end,2:end),2);
 perempty = (perempty./5)*100;
result=[gene(2:end,2:end) perempty]
but get error  ,getting all values  as zeros

Best Answer

result = gene;
for jj = 1:numel(gene)
    emptycells = cell2mat(cellfun(@(x) ~isempty(x),result{jj},'un',0));
    perempty = sum(emptycells(2:end,2:end),2)./5*100;
    result{jj} =[result{jj} [{''};num2cell(perempty)]];
end
