| If we want to restore the original indices of `AO`, we may wrap an `OffsetArray` around the `Diagonal` as: | ||
|
|
||
| ```julia | ||
| julia> Origin(AO)(D) | ||
| 4×4 OffsetArray(::Diagonal{Float64, Vector{Float64}}, 0:3, 0:3) with eltype Float64 with indices 0:3×0:3: | ||
| 1.0 ⋅ ⋅ ⋅ | ||
| ⋅ 6.0 ⋅ ⋅ | ||
| ⋅ ⋅ 11.0 ⋅ | ||
| ⋅ ⋅ ⋅ 16.0 | ||
| ``` |

For the specific 1-based case, I somehow feel the approach in #248 is more useful.
D = no_offset_view_apply(AO) do A
# do all the normal linear algebra thing in 1-based case
Diagonal(A)
end

It certainly seems useful, might be worth pushing it along.
