C = rand(10,2) ;
plot(C(:,1),C(:,2),'o','Markersize',10)
If you want circle with given radius R.
C = rand(10,2) ;
R = 4 ;
th = linspace(0,2*pi) ;
x = R*cos(th) ;
y = R*sin(th) ;
figure
hold on
for i = 1:10
xc = C(i,1)+x ;
yc = C(i,2)+y ;
plot(xc,yc)
end

Thank you so much, it worked perfectly with me, but can you please explain briefly what does each variable represent?
