Hi all,

I use the following script to write a 2D array. I wonder if there is
improvement for them.

Thanks,

Li

############script##########
data_all=[
        (1..10).to_a,
        (1..10).to_a,
        (1..10).to_a,
         (1..10).to_a
         ]# a 2D array


File.open('test3.txt','w') do |a_f|
       data_all.each do |row |
              row.each {|e| a_f.print e ;   a_f.print "\t"}
              a_f.puts
       end

end
