it does. try it.
@blueberry it seems to just be adding all 3 vectors:
(axpy (dv 1.0 1.0) (dv 2.0 2.0) (dv 3.0 3.0))
=> #RealBlockVector[double, n:2, stride:1]
[ 6.00 6.00 ]expected [5.00 5.00]
oh nevermind, alpha is supposed to be a scalar.
it can also be a vector. you decide 🙂
maybe a silly question, but why doesn't axpy in neanderthal have an alpha parameter?
