Then you open file in write mode 'w' old data will ber overwritten and you have 
a for loop open/close it several time. Below should work better, first open 
once then save all values and last close once.

  fprintf ( "Temperature =% 3.0f \ n" , temp);
  [fid1, msg1] = fopen ( 'file1.csv' , 'w' );
  for
    fprintf (fid1, 'temperature' );
    fprintf (fid, '% 3.0f' , temp);
    fprintf (fid, '\ n' );
  end
  fclose (fid);
