How about this?
[x,y,z] = sphere;
x = x*650000;
y = y*650000;
z = z*650000;
figure
surf(x+650000,y+650000,z+650000)

Try this:
% Make unit sphere
[x,y,z] = sphere;
% Scale to desire radius.
radius = 650000;
x = x * radius;
y = y * radius;
z = z * radius;
% Translate sphere to new location.
offset = 6500000;
% Plot as surface.
surf(x+offset,y+offset,z+offset)
% Label axes.
xlabel('X', 'FontSize', 20);
ylabel('Y', 'FontSize', 20);
zlabel('Z', 'FontSize', 20);
axis equal;

I don't know from that function, but you can of course easily generate your own coordinates on the shell of the sphere. For any given z value, it's simply a circle. See the FAQ:

That is one way to use plot3() to draw a spherical shell. Once you have the x,y,z data, you can offset it to the desired center.
If it's not actually necessary to use plot3() specifically, or if the sphere needs to be drawn in some other manner, then you'll have to say.

can you please tell nearest neighbour and contact distance distribution using binomial point process
