MATLAB: Plotting 3d Sphere with specific radius

Question

 Hello!

I am trying to plot a sphere in 3D. This is what i know so far.

[x,y,z] = sphere; surf(x+a,y+b,z+c);

now i know that (a b c) means that its a shift in the x y and z axis respectively but it also affects the radius at the same time. How can i create a shift like mention above but also scaling down the radius to something lower than 1?

Cheers!

Hi,

maybe by specifying the radius as a scaling factor:

 surf(x*r+a, y*r+b, z*r+c);
 axis equal;
