Higher level functions in the Vector API

[Paul Sandoz]

Hi Sam,

At the moment we are currently prioritizing work on Vector API, getting the implementation in shape and aligned with Valhalla. It's fantastic that developers are experimenting, providing feedback, and implementing functionality using the Vector API that was not possible before. Perhaps there will be some consolidation in the community with a useful library published on maven?

It’s easy to underestimate the work required to devise/include such APIs in the platform that are in effect BLAS-like level 1 and level 2 functionality (with higher levels waiting and asking to join the party). My sense is before we consider adding such support in the platform (if at all) we need to think more broadly about numerics, arrays, matrices, and tensors.

I don’t have anything concrete right now about such broader thinking, but here is an example of me playing around to get experience in this area:
