I want to obtain D.diag for a Diagonal matrix D, except I’m not sure if this is public. Using diag(D) allocates unnecessarily in certain cases (as it uses similar to ensure type-stability). julia> D = Diagonal(3:4) 2×2 Diagonal{Int64, UnitRange{Int64}}: 3 ⋅ ⋅ 4 julia> diag(D) 2-element Vector…

How to obtain the diagonal vector of a Diagonal matrix without allocations?

Evidently parent returns this

julia> parent(D)
3:4
