Create a vector of vectors.  You can use lua_rawseti to populate the
vectors.

/* matrix */
lua_newtable(L);

/* first vector */
lua_newtable(L);
/* populate first vector here ... */

lua_rawseti(L, -2, 1);

/* second vector */
lua_newtable(L);
/* populate second vector here ... */

lua_rawseti(L, -2, 2);

/* etc. */

/* matrix is at top of stack */
return 1;
