voronoi

PURPOSE ^

% plots voronoi diagram of points @code{(@var{x}, @var{y})}.

SYNOPSIS ^

function [vvx, vvy] = voronoi (varargin)

DESCRIPTION ^

% -*- texinfo -*-
% @deftypefn {Function File} {} voronoi (@var{x}, @var{y})
% @deftypefnx {Function File} {} voronoi (@var{x}, @var{y}, 'plotstyle')
% @deftypefnx {Function File} {} voronoi (@var{x}, @var{y}, 'plotstyle', @var{options})
% @deftypefnx {Function File} {[@var{vx}, @var{vy}] =} voronoi (@dots{})
% plots voronoi diagram of points @code{(@var{x}, @var{y})}.
% The voronoi facets with points at infinity are not drawn.
% [@var{vx}, @var{vy}] = voronoi(@dots{}) returns the vertices instead of plotting the
% diagram. plot (@var{vx}, @var{vy}) shows the voronoi diagram.
%
% A fourth optional argument, which must be a string, contains extra options
% passed to the underlying qhull command.  See the documentation for the
% Qhull library for details.
%
% @example
% @group
%   x = rand (10, 1);
%   y = rand (size (x));
%   h = convhull (x, y);
%   [vx, vy] = voronoi (x, y);
%   plot (vx, vy, '-b', x, y, 'o', x(h), y(h), '-g')
%   legend ('', 'points', 'hull');
% @end group
% @end example
