I have these points

Ax=2:4:14;
Ay=2:4:14;
Z=rand(4,4)+20;

I would like to plot the surface in 3D but not as a unite surface but rather multiple individual surfaces. I would like each point to be a square surface of surface area=4*4, parallel to xy axes where Ax and Ay is the centre of each square surface.

I tried the below but no luck

surf(Ax,Ay,Z)
bar3(Z,4)

I am not certain what you want.

This should get you started:

Ax=2:4:14;
Ay=2:4:14;
figure(1)
for k1 = 1:length(Ax)
    surf(cumsum(ones(4),1)+Ax(k1), cumsum(ones(4),2)+Ay(k1), zeros(4)+rand)
    hold on
end
hold off
grid on
