36 %% Description of functions operating on planar lines.
38 % The term 'line' refers to a planar straight line, which is an unbounded
39 % curve. Line segments defined between 2 points, which are bounded, are
40 % called 'edge', and are presented in file 'edges2d'.
42 % A straight line is defined by a point (its origin), and a vector (its
43 % direction). The different parameters are bundled into a row vector:
44 % LINE = [x0 y0 dx dy];
46 % A line contains all points (x,y) such that:
49 % for all t between -infinity and +infinity.
