files = dir('*.txt') ;
N = length(files) ;
SS = cell(N,1) ;
fid0 = fopen('myfile.txt','w');
for i = 1:N
    fid = fopen(files(i).name,'r') ;
    S = textscan(fid,'%s','delimiter','\n') ;
    SS = S{1} ;
    fclose(fid) ;
    for j = 1:numel(SS)
        fprintf(fid0,'%s\n',SS{j}) ;
    end
end
fclose(fid0) ;
