-% Compander function is defined in three radial zones.
-% 1. From 0 to radius r0, the compander function
-% is a second-order polynomial intersecting the points (0,0)
-% and (r0, r0), and with a slope B in (0,0).
-% 2. From r0 to r1, the compander is a third-order polynomial
-% intersecting the points (r0, r0) and (r1, r1), and with the
-% same slope as the first part in the point (r0, r0) and slope
-% equal to 1 in (r1, r1).
-% 3. For radii larger than r1, the compander function is the
-% unity scale function (no scaling at all).
