You can do it using the reshape function.

B = reshape(A,9,3);

vector2D = cat(2,vector3D(:,:,1),vector3D(:,:,2),vector3D(:,:,3))

or

vector2D = cat(1,vector3D(:,:,1),vector3D(:,:,2),vector3D(:,:,3))

The previous will arrange the 2D vectors along rows, while the later will arrange them allong colums
