36 %% Description of functions operating on planar rays
38 %% A ray is defined by a point (its origin), and a vector (its
39 %% direction). The different parameters are bundled into a row vector:
40 %% @code{RAY = [x0 y0 dx dy];}
42 %% The ray contains all the points (x,y) such that:
47 %% Contrary to a (straight) line, the points located before the origin do
48 %% not belong to the ray.
49 %% However, as rays and lines have the same representation, some functions
50 %% working on lines are also working on rays (like @code{transformLine}).
