It would be better if you upload your Matlab code.

function atomplot(pos)

%The function atomsplot plots spheres at the 3dimensional coordinates specified by the vectors

%x,y and z in pos.

%R - radii of the atoms

%T - atom type an integer from 1 to the number of types of atoms

R=0;

[Xs,Ys,Zs]=sphere(25); %Creates spheres of precision 25

Xs=Xs*R; %creates the radii size of the spheres

Ys=Ys*R;

Zs=Zs*R;

clf reset

ball=zeros(1,size(pos,1));

for t=1:size(pos,1)

ball(t)=surf(Xs+pos(t,1),Ys+pos(t,2),Zs+pos(t,3)); %plots the balls

set(ball(t),'facecolor','r',...

'edgecolor','none','facelighting','phong' );

%sets colors and effects for the ball plotting
