I want to plot two spheres. It appear as ellipses. Can anyone help me?

a=1;

L=0.1;

dd=5;

c =-a/L;

b =a/L;

m =a*60; %

[x,y]=meshgrid((c+dd:(b-c)/m:b),(c:(b-c)/m:b)');

[I, J]=find(sqrt(x.^2+y.^2)<(a-0.1));

if ~isempty(I)

x(I,J) = 0; y(I,J) = 0;

end

r=sqrt(x.^2+y.^2);

t=atan2(y,x);

r2=sqrt(r.^2+dd.^2-2.*r.*dd.*cos(t));

zet=(r.^2-r2.^2-dd.^2)./(2.*r2.*dd);

Adding

axis('equal')

solves it!

a=1;
L=0.1;
dd=5;
c =-a/L;
b =a/L;
m =a*60; %
[x,y]=meshgrid((c+dd:(b-c)/m:b),(c:(b-c)/m:b)');
[I, J]=find(sqrt(x.^2+y.^2)<(a-0.1));
if ~isempty(I)
    x(I,J) = 0; y(I,J) = 0;
end
r=sqrt(x.^2+y.^2);
t=atan2(y,x);
r2=sqrt(r.^2+dd.^2-2.*r.*dd.*cos(t));
zet=(r.^2-r2.^2-dd.^2)./(2.*r2.*dd);
