how to draw a regular polygon with polarplot command?
i'll use input command for n and R.
(n is the number of vertices, R is the distance between the vertex and the center)
conditions are
  1. center is 0,0
  2. the distance between vertex and center is R.

What have you tried so far? Are you stuck on the math for converting a regular polygon to polar form? Or on using polarplot specifically?

@John Morris
sorry i forgot the code
prompt_n=('Input n what you want(n>=3): ');
prompt_R=('Input R what you want(R>0): ');
na=input(prompt_n);
R=input(prompt_R);
n=round(na);
theta = 0:pi/90:2*pi;
pgon = nsidedpoly(n,'Center',[0,0]);
if n>3
plot(pgon)
hold on
polarplot(theta,R)
else
disp('끝냅시닷:p');
end

After drawing the polygon, I tried to write holdon on the polar coordinates, but it didn't work

Convert polar coordinates to cartesian and then plot.
prompt_n=('Input n what you want(n>=3): ');
prompt_R=('Input R what you want(R>0): ');
na=input(prompt_n);
R=input(prompt_R);
n=round(na);
theta = 0:pi/90:2*pi;
pgon = nsidedpoly(n,'Center',[0,0]);
x = R*cos(theta) ;
y = R*sin(theta) ;
if n>3
plot(pgon)
hold on
plot(x,y)
else
disp('끝냅시닷:p');
end
