The core.matrix API should be 100% pure Clojure. Some of the implementations are JVM specific however (e.g. support for fast operations on Java double arrays etc.)
So... it probably needs a bit of hacking to make it work on ClojureScript with some form of conditional compilation setup. If anyone fancies taking that on, I'd be happy to support.
