OK, I found it. It is here:
https://github.com/cnuernber/dtype-next/blob/5e81b0d32ad2f47479a698a244805b5f1abc06f8/src/tech/v3/datatype/functional/vecopt.clj#L48
from tech.ml.dataset.
Indeed!
> (tech.v3.datatype.functional/dot-product [1 2 3] [4 5 6])
32.0
from tech.ml.dataset.
Also, without the lib (in Clojure):
> (reduce + (map * [1 2 3] [4 5 6]))
32
This, of course, behaves differently in terms of types and performance, but may also be useful in some cases.
