If I have my own type, which can be indexed like an array, and has a length. How can I get broadcast to work with it as an array-like type instead of a scalar? I can only find useage guides in the language manual for vectorised ops and broadcasting, nothing about extending the broadcast method to ne…

I’m a little fuzzy on exactly what you are trying to do, but you have several options. First of all, as I understand it, broadcast methods are intended for cases where there is an actual underlying loop. If your method is abstract, and does not involve a loop, it is better to write dedicated, undo…

The easiest way would be to make your type <: AbstractArray and define size and getindex. That should enable broadcasting to just work. Or is your type not sufficiently array-like for it to be an AbstractArray?

My type does many things an array (actually more like a vector) does, insofar as indexing and having length and eltype and so on. So it has those behaviours, but also a lot more that means it would not be neatly bike-shedded under AbstractArray. I’d like to know what one would do to allow broadcasti…
