fid = fopen('YourFile.dat', 'w');
fprintf(fid, '%d qid:1 1:%6.4f 2:%6.4f 3:%6.4f 4:%6.4f\n', C.');
fclose(fid)

The data is not stored in one row: you are using an obsolete editor to look at the file. Microsoft started replacing NotePad by 1997.
If you need to keep using 20 year old software, then replace the 'w' with 'wt'
