You can follow this:

Consider the center is at [c1,c2,c3]. The number of faces as r.

[x,y,z] = sphere(r);
surf(x+c1, y+c2, z+c3)

These two lines of code are enough to plot a sphere using the surf command.

For instance, if C=[2,2,2] and r=30 the result is as follows:

enter image description here

This is a sphere of radius 1 centered at [2,2,2]. To have a sphere with an arbitrary radius R, you should multiply the [x,y,z] values by R before adding the center.
