The right tool for the right job (TM). Octave is definitely not the
right tool for this (looping is notorious, as with matlab or R), you
should use external utilities. in perl, to split by white spaces

# perl -aF"\s" -ne 'print "$F[0]\n";' < input

then just read the splitted stuff (iirc octave can interface with the shell=
 too)
