| #include <octave/oct-map.h>

| ~  octave_value_list array;
| 
| ~  Octave_map map1, map2;
| 
| ~  map1.assign("name", octave_value("hello"));
| ~  map1.assign("type", octave_value("int32"));
| 
| ~  map2.assign("name", octave_value("world"));
| ~  map2.assign("type", octave_value("int32"));
| 
| ~  array(0) = map1;
| ~  array(1) = map2;
| 
| ~  retval(0) = array;
| ~  return retval;
| }
| 
| 
| $ mkoctfile test.cc && echo test | octave -q
| ans =
| (
| ~  [1] =
| ~  {
| ~    name = hello
| ~    type = int32
| ~  }
| 
| ~  [2] =
| ~  {
| ~    name = world
| ~    type = int32
| ~  }
| 
| )

Yes, this works, but why would you want to do that when Octave_map is
already capable of holding structure arrays?
