computation of conformal maps to polygonally bounded regions

function handles = plot(p,varargin)
%PLOT Plot a polygon.
%   PLOT(P) plots the polygon P (draws the sides).
%   
%   PLOT(P,'num') or PLOT(P,'lab') also plots dots for the vertices and
%   numeric labels. For infinite vertices, two numeric labels are
%   printed.
%   
%   H = PLOT(P) returns a vector of handles to the sides drawn. H =
%   PLOT(P,'num') returns a structure; H.side is a vector of side
%   handles, and H.label is a 2-column array of vertex dot and label
%   handles (each vertex has two graphical objects).
