How can I generate a square lattice undirected graph?

Hi,

How can I generate a square lattice undirected graph? I tried this:

n = 10;
A = delsq(numgrid('S',n+2));
G = graph(A,'omitselfloops');
plot(G)

But the links do not look straight, right? And the graph looks like a plateau.

Thanks!

Okay, when I checked the XData and YData using :

p = plot(G);
p.XData
p.YData

I found that nodes are not evenly spaced. Can you help me on this please?

n = 10;
A = delsq(numgrid('S',n+2));
G = graph(A,'omitselfloops');
h = plot(G);
h.XData = floor((0:99)/10);
h.YData = rem((0:99), 10);
axis equal

Thank you so much.
