I think you want LinearAlgebra.reflectorApply!. Unfortunately no documentation…
No documentation found.
LinearAlgebra.reflectorApply! is a Function.
# 1 method for generic function "reflectorApply!":
 reflectorApply!(x::AbstractVector, τ::Number, A::AbstractMatrix) in LinearAlgebra at /Users/sheehanolver/Projects/julia-1.7/usr/share/julia/stdlib/v1.7/LinearAlgebra/src/generic.jl:1518
Thanks! I’ll take a look at the implementation to see if it’s doing what I need
But I was more wondering if there was some generic type that used this functionality through an implementation of the array interface. Then I could just plug in its representation where I need it. I guess this doesn’t exist?
