cartesian clj/s

(cartesian x-coll)

(cartesian x-coll & colls)

computes the cartesian product of two or more sequences. If only one sequence is provided then a sequence of each element wrapped on a list is returned. Note that the cartesian product of an empty sequence is a sequence with an emtpy list, since there is one way to take the cartesian product of no lists

find-boundaries clj/s

(find-boundaries p2p-dist)

Given a point to point distance matrix (p2p-dist) obtained from 2 curves P and Q find the nearest point to P's start/end in Q (resp. from Q in P)

part-curve-dist clj/s

(part-curve-dist P Q dist-fn all-bounds)

calculate the link distance and the coupling sequence of all possible boundaries (all-bounds). Returns all the partial frechet distances and their couplings

valid-bounds? clj/s

(valid-bounds? [is js ie je])

check if the current bounds are valid. Valid bounds are such that the curve contains at least 2 points
