I thought that prefer_column_vectors affected the output
of things like    x = y(:), and I was trying to duplicate this
functionality in the sparse functions.  I just checked, and it
turns out that octave doesn't work this way, so I don't need the
variable.

Thanks. I didn't like having to do so much casting.

One more question:

3. Previously, (ie in 2.1.19) I was able to get at 
   index operations working using something like:

  octave_value_list
  octave_integer::do_index_op (int, const octave_value_list& idx)

   but this no longer works. 
   What is the new way to do index operations?

Thanks
