Topic: ✔ Broadcasting over custom array type


view this post on Zulip Brenhin Keller (Jun 05 2022 at 03:44):

Is there a method you can implement if you want a broadcast over a custom array type to return an array of that is also of your custom array type instead of a Base.Array?
i.e.

A::MyArray
B = A .+ 5 # Want this to return a `MyArray`  too

You need to overload Base.Broadcast.broadcasted

it's a little dated by now (especially in regards to "put @inbounds there"), but the talk is still the best summary of custom arrays & broadcasting that I know of
