So I've made significant headway on cythonizing a pdist function that ignores NaNs. You can see the results here: http://nbviewer.ipython.org/gist/Midnighter/b81d5732a0ef88f2e185 Two questions remain: 1) Can I somehow make use of the distance measures defined in scipy/spatial/src/distance.c? 2) Does anyone know if numexpr could be used to compute the above pairwise distances in parallel? Thank you again.
