Note that Apple has a similar library called vForce:
I think these libraries use several techniques and are not necessarily
dependent on SSE. The apple versions appear to only support float and
double (no complex), and I don't see anything about strided arrays.
At one point I thought there was talk of adding support for vForce
into the respective ufuncs. I don't know if anybody followed up on
