%  POLYPLOT - 2-D Polygon plot
%
%  Usage:       hh = polyplot(pts,varargin)
%
%  Arguments:   pts     - the 3xn or 2xn vertices of a polygon
%               varargin- variable inputs for plot options, eg. 'ro:'
%                         see PLOT for more details
%
%  Returns:     hh      - a vector of handles to the displayed triangles

function hh = polyplot(pts,varargin)

h = plot(x,y,varargin{:});

if nargout == 1, hh = h; end
