WRT Incanter, you might find some high-performance libraries interesting: http://neanderthal.uncomplicate.org http://neanderthal.uncomplicate.org and http://git

WRT Incanter, you might find some high-performance libraries interesting: http://neanderthal.uncomplicate.org http://neanderthal.uncomplicate.org and http://github.com/uncomplicate/bayadera http://github.com/uncomplicate/bayadera. They are much more low-level than Incanter, but also orders of magnitude faster, and intended as a foundation for the Incanter-like libraries to be built on top. They are actively developed.
