plotcirc.m

基于＂trace transform＂的识别２Ｄ图像的Ｃ＋＋源程序

function plotcirc(c)
   I=find(c<0); N2pi=length(c);
   figure;
   plot(complex(0),'ro'); hold on;
   polar_abs_c=abs(c).*exp(1i*(0:N2pi-1)/N2pi*2*pi);
   plot(polar_abs_c,'.-');
   if ~isempty(I),plot( abs(c(I)).*exp(1i*(I-1)/N2pi*2*pi),'g.' );
   end
   axis equal;
