Access data in an NDArray

[Fredrik Lingvall]

For a Matrix I can get a pointer to the data using, for example,

const Matrix tmp = args(0).matrix_value();
A_M = tmp.rows();
A_N = tmp.cols();
A = (double*) tmp.fortran_vec();

Now I want to do that for a (3D) NDArray, that is, I want
a pointer to each (2D) Matrix in the NDArray. How do
I do that? Is the data stored in one consecutive block so
that I can use pointer arithmetics to find each Matrix in
the NDArray?

Fredrik
