%% Plot Multiple Spheres
% Define x, y, and z as coordinates of a sphere.

[x,y,z] = sphere;

%
% Plot a sphere centered at the origin. Plot two more spheres centered at (3,-2,0) and (0,1,-3).

figure
surf(x,y,z)

hold on 
surf(x+3,y-2,z) % centered at (3,-2,0) 
surf(x,y+1,z-3) % centered at (0,1,-3)
