MATLAB: Six pointed star

hexagramhomeworkpolarsix-pointedstar

I need to know how to plot a six pointed star using polar coordinates. I know I need to use the hold on/hold off funcion but I'm not really sure what else?

No, you do not need hold. You can modify the example you find in help polar.

MATLAB: How to use the data, but no polar function, to make polar plot

I would use polar to plot the data; however it looks like R2016a has a preferred option -- polarplot ( doc ).

With polar, you could try

 theta = linspace(0,2*pi,1e3); % more values yeilds a smoother plot
 r = nan(size(theta)); % pre-allocate r
 r(theta<pi/2) = 1;
 r(theta>=pi/2&theta<pi) = 2;
 r(theta>=pi&theta<3*pi/2) = 3;
 r(theta>=3*pi/2) = 1.5;
 r(end) = 1; % makes it a closed loop
 polar(theta,r)
