Connect all dots I polarplot

Hello, I would like to connect the last item with the first one, so I get a “circle”. I know how to connect the dots at the polarscatter but how do I connect the last dot with the first one without changing the vector s?

clc;
clear all;
r=[10:36:360]
r = r/360*2*pi
s=[5,3.5,5,4,4,3.5,4,4.2,4.7,4]
polarplot(r,s,'-x')

Like this?

r=[10:36:360 10];
r = r/360*2*pi;
s=[5,3.5,5,4,4,3.5,4,4.2,4.7,4, 5];
polarplot(r,s,'-x')

yes, but now you changed the vector s and addeed an other dot. i want to do that with oucht changing the vector manually

" but now you changed the vector s and addeed an other dot"

Why don't you want to do that?

Here's another possibility:

r=10:36:360;
r = r/360*2*pi;
s=[5,3.5,5,4,4,3.5,4,4.2,4.7,4];
r2 = [334 10];
r2 = r2/360*2*pi;
s2 = [4 5];
polarplot(r,s,'-bx', r2, s2, '-bx')

that should work. thx
