hi. i tried to plot a sphere with sphere function. but the sphere was very ugly. and it was more like an ovoid. plz help me to plot a nice sphere. something like this pic
a=[0 0 0];
[e,f,g] = sphere(30);
e=e*0.3;
f=f*0.3;
g=g*0.3;
s1=surf(e+a(1),f+a(2),g+a(3),'FaceAlpha',0.2,'FaceColor','r')

If you don't have access to the cuteSphere toolbox, you can just use this line of code below to make the sphere appear as a sphere.
%[your plotting code]
axis equal
The reason your sphere appeared as an ovoid is because the data aspect ratio is not equal.
