I have a problem with feval function of using c++ and octave

[jessada2534]

after I collected and edited this code from somewhere, it could be compiled
but when run the function "feval" throws an exception like data out-of-bound
or something like that. here is the code

-------------------------------------------------------------------------------------
#include <iostream>
#include <octave/oct.h>
#include <octave/octave.h>
#include <octave/parse.h>


using namespace std;

int main (const int argc, char **argv)
{
        const char *argvv[] = {"", "--silent"};

   octave_main(2, (char **)argvv, true);

   octave_idx_type n = 2;
   Matrix a_matrix = Matrix(1, 2);
   a_matrix(0) = 2;
   a_matrix(1) = 3;

   octave_value_list in = octave_value(a_matrix);
   octave_value_list out = feval("gg", in, 1);

   return 0;
}
------------------------------------------------------------------------------

and this is the m-file of gg.m file
-----------------------------------------------------------------------------
function [a] = gg(c)
   c = c+1;
   a = c;

endfunction
------------------------------------------------------------------------------

Did I do something wrong? or Is there another way to call m-file from c++
program

Thanks
Jess
