My benchmarking of eigen has not shown positive results. Similar
methods that we have in VOLK run much, much faster than the eigen
functions.
If you're using eigen because it already has functionality you need,
I'd recommend you starting with numpy/scipy in Python and then migrate
that the a more optimized C++ block using VOLK and skip the step
altogether of trying to link against eigen.
