th = [0 60 150 210 300 360];
r  = [0  0  38  38   0   0];

angs = linspace(0, 360, 500);
radii = interp1(th, r, angs);

angs_rad = angs .* pi/180;     %convert to radian

polar(angs_rad, radii)

I think you will need to adjust the radius profile.

Thank you so much sir, you are the backbone of society and the unsung hero of our time.

how did you adjust the radius profile?
