Nice example. Thank you. Pairing a bunch of toy m-functions with the
corresponding oct-functions would make a nice document.

Since I can only index a NDArray with a single index, how do I pull
out an entire 2D slice of a 3D array?

n = [3 2 4];
x = rand(n);

I want y = x(:,:,j), so in an oct function would I have to do the equivalent of

ind = (j - 1)*n(1)*n(2) + (1:(n(1)*n(2)));
y = x(ind);
y = reshape(x,n(1),n(2));

or if reshape is not available loop over the rows and columns of y?
