i have just loaded the file only

for k=0:6 
[status, msg, msgID] = mkdir( num2str(k )) ;
end

opt = {'Delimiter',',','Bufsize',pow2(14)};
  [fid,msg] = fopen('data.csv','rt '); 
  assert(fid>=3,msg ) 
  hdr = regexp(fgetl(fid),'\S+','match '); 
  C = textscan(fid,'%d%s%s',opt {:}); 
  fclose(fid ); 
  fun = @(s)sscanf(s,'%d ').'; 
  C{2} = cell2mat(cellfun(fun,C{2},'uni',0));
