Follow-up Comment #7, bug #41799 (project octave):

Overall, I think the sparse documentation could be enhanced.  I did a bit of
that, increasing the number of seealso links between related sparse functions,
in this changeset (http://hg.savannah.gnu.org/hgweb/octave/rev/53af80da6781). 
For this case, I think it would be good to write up your code usage as a
second version of case #1, explaining that it is more efficient than the
implementation with ColumnVectors (4 bytes rather than 8 bytes per index), but
that it still suffers from the problem of duplicate values in memory at the
same time.
