th = linspace(0,2*pi,50);
r = 10;
polar(th,r+zeros(size(th)))

I have used this script and it works (changed polar to polarPlot) but can't run it as a function. Any ideas?

%need centres for demo purposes
xc = randn() * 5; yc = randn() * 5;
%the work
th = linspace(0,2*pi,50);
r = 10;
[x,y] = pol2cart(th,r);
[th1, r1] = cart2pol( x+xc, y+yc );
polar(th1, r1);
