function edges2d(varargin)
%EDGES2D  Description of functions operating on planar edges.
%
%   An edge is represented by the coordinate of its extremities:
%   EDGE = [X1 Y1 X2 Y2];
%
%   Centered edges are sometimes used (for example for representing main
%   axes of an ellipse or an oriented box). Centered edges are represented
%   by their center, their length, and their orientation (counted in
%   degrees and counter-clockwise).
%   CEDGE = [XC YC LEN THETA];
%
%   A set of edges is represented by a N-by-4 array, each row representing
%   an edge.
