Unfortunately, it was +not possible to easily link against this library: in 1.4.0, support has been +added to numpy.distutils so that 3rd party can reuse this library. See coremath +documentation for more information. + Improvements ============ #. numpy import is noticeably faster (from 20 to 30 % depending on the platform and computer) + #.
