carocad.frechet.shared — net.clojars.carocad/frechet 0.14.1

Common functions used by both frechet and partial frechet distance. Internal implementations; subject to breaking changes without warning!

bounds clj/s

(bounds array-2d)

returns a vector of [min-i min-j max-i max-j] where i and j are the row and column indexes on the 2D array

column clj/s

(column array-2D j)

find-sequence clj/s

(find-sequence CA)

Given a link-distance 2D array (of doubles) CA finds 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.

get2D clj/s

(get2D array2D [i j])

link-matrix clj/s

(link-matrix P Q dist-fn)

Given 2 curves P an Q compute the link distance between them using dist-fn. Returns a 2D array of doubles.

point-distance clj/s

(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

row clj/s

(row array-2D i)
