Pleased to announce a new release of vectorz-clj, a fast and idiomatic matrix/vector maths library for Clojure.
https://github.com/mikera/vectorz-clj Key developments: - Update to core.matrix 0.5.0 for the latest core.matrix features - Improved operator support: ability to combine operators, take derivatives etc. - Basic support for N-Dimensional double arrays - Performance enhancements (see e.g.: http://bit.ly/Zt3usC) - Experimental sparse matrix support (via Matrixx/createSparse) vectorz-clj is a complete core.matrix implementation. So if you use it via the core.matrix API, you maintain the flexibility to switch to other core.matrix implementations in the future (e.g. Clatrix for native JBlas libraries). For more information on core.matrix see: https://github.com/mikera/matrix-api A core.matrix code example using vectorz-clj: ;; define a 2x2 matrix M (def M (matrix [[1 2] [3 4]])) M => #<Matrix22 [[1.0,2.0][3.0,4.0]]> ;; compute the inverse of M (inverse M) => #<Matrix22 [[-2.0,1.0][1.5,-0.5]]> ;; multiply M with a vector (core.matrix supports regular Clojure vectors!) (* M [1 2]) => #<Vector2 [-3.0,-5.0]> ;; multiply M with a 2x4 matrix (* M [[1 2 3 4] [5 6 7 8]]) #<Matrix [[11.0,14.0,17.0,20.0][23.0,30.0,37.0,44.0]]> Note the use of specialised classes for (Vector2, Matrix22 etc.): these enable much higher performance and better memory usage for the common sizes of small matrices and vectors (used for 2D / 3D maths etc.) -- -- You received this message because you are subscribed to the Google Groups "Clojure" group.
