# How can I fill a circle after using the viscircles command?

I am plotting some circles with certain radius. I want to fill the circles depeding on their colours. I have used the 'viscircle' command of MATLAB. So how can I improve my code? It seems like the facecolour input is not given for viscircles.
for l=1:length(newlist(:,1))
centers= [newlist(l,1) newlist(l,2)];
r=newlist(l,3);
if r == 1.5
k= [1 0 1]
elseif r==3
k=[0 1 0]
end
viscircles( centers, r,'LineStyle','-','LineWidth',0.1,'EdgeColor',k,'Facecolor',k);
%theta = 0 : 0.01 : 2*pi;
%x = r*cos(theta) + xcenter;
%y = r*sin(theta) + ycenter;
end

You'll probably have to use rectangle, which can display circles with solid colors.

Yes, I have changed the code.
