No you have to loop over the elements.. However you can access the
*uint16 of the array itself with something like
uint16NDArray A (dim_vector(11,1));
const uint16 *cp = A.fortran_vec();
uint16 *p = A.fortran_vec ();
Note the const version is useful if "A" comes from somewhere else in
Octave and you'll only be reading the data. You can avoid a copy of A
internally in Octave in that way if the reference point to the
underlying data of "A" is greater than 1.
