bound-zero clj

(bound-zero mtx)

compute the get-bounds of a matrix (mtx) taking into account that mget is zero indexed

compute-CA! clj

(compute-CA! CA p2p-dist i-start j-start i-end j-end)

mutates CA between the boundaries specified by i,j to calculate the link distance

find-sequence clj

(find-sequence CA)

(find-sequence CA [i-start j-start i-end j-end])

Given a link-distance matrix CA find the path enclosed by the limits i-start j-start i-end j-end that minimizes the distance between the two curves from which CA was created.

link-matrix clj

(link-matrix p2p-dist)

(link-matrix p2p-dist limits)

calculate the link distance among all possible discrete parametrization of the curves P and Q using dist-fn. The discrete frechet distance is returned along the coupling sequence.

point-distance clj

(point-distance P Q dist-fn)

computes the distance between all the possible point combinations of the two curves P and Q using the dist-fn
