|

| 
| octave_value_list GetSubstruct() {
|    Octave_map tmp;
|    octave_value_list substruct;
| 
|    for (int i=0; i < 10; i++) {
|      tmp.assign("a", i);
|      substruct(i) = tmp;
|    }
| 
|    return substruct;
| }
|

It's not clear to me exactly what data structure you are trying to
create here.  Can you post some Octave code that creates a small
structure with the key elements that you would like to construct
using C++?
