Hi All, Pleased to announce the latest release of vectorz-clj, a high performance vector and matrix math implementation for Clojure.
GitHub site: https://github.com/mikera/vectorz-clj Clojars: https://clojars.org/net.mikera/vectorz-clj Key features: a) 100% pure JVM code (no native libraries required) b) Supports a clean, functional, idiomatic style of vector and matrix maths in Clojure c) Currently the most complete implementation of the "core.matrix" API for Clojure numerics d) Very fast - designed for games, simulations, machine learning applications etc. For an idea of performance, it is worth comparing with regular Clojure vectors: (let [a [1 2 3 4 5 6 7 8 9 10] b [1 2 3 4 5 6 7 8 9 10]] (c/quick-bench (dotimes [i 1000] (vec (map clojure.core/+ a b))))) ;; => Execution time mean per addition : 1221 ns Using vectorz-clj to do the same additions is about 15-20x faster: (let [a (matrix :vectorz [1 2 3 4 5 6 7 8 9 10]) b (matrix :vectorz [1 2 3 4 5 6 7 8 9 10])] (c/quick-bench (dotimes [i 1000] (+ a b)))) ;; => Execution time mean per addition: 68 ns If you are willing to abandon immutability and use mutable vectors, you can go faster still: (let [a (matrix :vectorz [1 2 3 4 5 6 7 8 9 10]) b (matrix :vectorz [1 2 3 4 5 6 7 8 9 10])] (c/quick-bench (dotimes [i 1000] (add! a b)))) ;; => Execution time mean per addition: 31 ns This is all still very much in early development, so feedback / ideas / code contributions all very welcome!
