This removes those type annotations that are never used in multiple dispatch. The common pattern of input types and output types (AbstractVector -> AbstractVecOrMat, AbstractMatrix -> AbstractMatrix) is consistent with
LinearAlgebra
, and is checked for at themul!
level. Afterwards, in_unsafe_mul!
the consistency of input and output types is never checked again. What matters is only (a) which map type we use, (b) to which array type we apply the map. In the 5-arg case, it is clear thatmul!
will only deliverNumber
s as fourth and fifth argument. I believe this improves readability quite a bit. I have used the opportunity to (hopefully) clearify the docs even more.
