2D random paths generator integrating leg's contraints

version 1.2 (59.1 KB) by

Generates random 2D leg'paths from departure to arrival integrating leg's constraints



View License

Generates random 2D-paths between start and finish nodes according to densities distribution given by matrix C with leg's contrainsts defined by the adjacency matrix I.

P = path_generator(start , finish , I , [C] , [K] , [V] , [delta]);


start Index of starting points (r x 1) where start(i) = 1,...,R, R = 8(Nx-2)(Ny-2) + 10((Nx-2)+(Ny-2)) + 12,
                    where Nx, Ny denote the number of nodes in x and y axis respectivly.
finish Index of arrival points (q x 1) where finish(i) = 1,...,R
I Index of neigbourds (D x R), where D = 8
C Probabilities matrix (D x R x L) such that sum(C,1) = 1 (default C is uniform pdf)
K Number of path's leg (at least the number of the shortest path, default K = 100)
V Number of path's to generate (default V = 1)
delta Transition legs'angles constraints matrix (D x D), i.e. delta(p_{k}|p_{k-1}) (default delta = ones(D,D));


P Path leg's indexes(K x L x V)

- Update inpoly and dijkstra
- Minor comestic changes and should be compatible with Linux/GCC
- Updade demo file


-add mexme_path_generator2
-update djikstra and inpoly algorithm

MATLAB Release
MATLAB 7.5 (R2007b)
