Great, thanks. I've now got indexing working on sparse variables.

However in order to implement an efficient indexing algorithm,
I need to sort the idx_vector, and then use the sort index
to build the extracted matrix.

After digging around in /usr/local/include/octave/idx-vector.h,
I found several methods on idx_vector which look promising.

I can use idx_vector::sort, but I need to get the sort index
as well.

Could you explain if any of the methods on idx_vector allow
