- This function calculates the directional distribution of points defined in  of a point process returning the distributions in matrix T.
- T = ddf(H, r1, r2)
T = ddf(H, r1, r2, N)
T = ddf(H, r1, r2, N, str)
[T, a] = ddf(H, ...)
- T=ddf(H, r1, r2) calculates the directional distribution T of points in B, type uint8, such that r1<=|x-y|<r2.
T=ddf(H, r1, r2, N) specifies the number of angular bins as N, (default=72).
T=ddf(H, r1, r2, N, str), when str="cluster", ddf calculates the direction distribution of daughter points about a parent point.
[T, a]=ddf(H, ...) returns the center angle for each bin of T in a.
