```I've rewroten the code with polar axes using epstk, the code

function [] = polares(z,n)

for k=0:n
theta(k+1)=((arg(z)+2*k*pi)/n);
rho(k+1)=abs(z);
end

eopen('polar.eps');
clf;
eglobpar;
ePlotTitleDistance = 25;
titulo = sprintf('Raices %d - esimas',n);
ePlotTitleText = titulo;
eaxespol([0 0.4 abs(z)],[0 round(180/n) 360]);
ePolarAngleGridColor = [0 0 1];
if(imag(z)==0)
leyenda = sprintf('Poligono Regular %d lados de z =
%.2f',n,real(z));
elseif(real(z)==0)
leyenda = sprintf('Poligono Regular %d lados de z = %.2f
i',n,imag(z));
else
leyenda = sprintf('Poligono Regular %d lados de z = %.2f + %.2f
i',n,real(z),imag(z));
end
epolar(theta,rho,leyenda,0,[0 0 1],1.25);
epolar;
eclose;
eview;
clear;
end

This is the best option beacuse polar plot is the natural plot for these
type of regular polygons, where the vertices are complex numbers with a
