36 %% Description of functions operating on circles
38 %% Circles are represented by their center and their radius:
40 %% One sometimes considers orientation of circle, by adding an extra
41 %% boolean value in 4-th position, with value TRUE for direct (i.e.
42 %% turning Counter-clockwise) circles.
44 %% Circle arcs are represented by their center, their radius, the starting
45 %% angle and the angle extent, both in degrees:
46 %% CA = [xc yc r theta0 dtheta];
48 %% Ellipses are represented by their center, their 2 semi-axis length, and
49 %% their angle (in degrees) with Ox direction.
50 %% E = [xc yc A B theta];
