FillArrays

Open willtebbutt opened this issue 5 years ago • 2 comments

There are currently instances when we want to use arrays of zeros in which size information is retained - this is not something supported by the Zero differential, but which is supported by FillArrays.jl's Zeros type. I would be nice to use this here, but are there perhaps issues with it not defining setindex?

FWIW, I'm very keen on having first-class AD support for FillArrays as I use them extensively in Stheno.jl, and Zygote.jl now makes use of them internally rather than rolling its own fill type.

tr is an example that should be FIllArrays. Zygote does so.
