How to compute a Hankel matrix for N-dimension ?

Hello everyone, I have a 4-dimension matrix A configured as follow :

[w x y z]=size(A);

where w=10; x=10; y=10 and z=10. Is there any matlab code/function to compute the hankel matrix of this 4-dimension matrix A ? Thanks for your help.

Not sure what is the Hankel in 4-D but by extension in 2D it should be something like this

w=5;
x=4;
y=3;
z=2;
b = rand(1,w+x+y+z);

[W,X,Y,Z] = ndgrid(1:w,1:x,1:y,1:z);
A = b(W+X+Y+Z)
