I'm trying to call some third-party code that expects a two- dimensional double array, and I can't figure out how to create and fill this in Clojure without a huge perf hit (which profiling shows to be coming from reflection):
user> (time (let [arr (make-array Double/TYPE 1)] (dotimes [_ 100000] (aset-double arr 0 0.0)))) "Elapsed time: 28.408 msecs" nil user> (time (let [arr (make-array Double/TYPE 1 1)] (dotimes [_ 100000] (aset-double arr 0 0 0.0)))) "Elapsed time: 3634.136 msecs" nil I've tried adding type hints like #^"[[D" to no avail. What am I missing here? BTW, I'm still on the pre-lazy SVN, waiting for the dust to settle.
