Try this:

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

  octave_value
  GetSubstruct (void)
  {
     Octave_map m;

     Cell tmp (dim_vector (10, 1));

     for (int i = 0; i < 10; i++)
       tmp(i) = i+1;

     m.assign ("d", tmp);

     return m;
  }

  DEFUN_DLD (TranslateSBML, , ,
    "TranslateSBML")
  {
     Octave_map m;

     m.assign  ("b", "B");
     m.assign ("c", GetSubstruct ());

     return octave_value (m);
  }
