Hi,
I have a following problem. I need to define a function, say f(a, b), where a and b are matrices. For this function, I want to define a gradient for Flux, therefore if one of those arguments are of type TrackedArray, they needs to be forwarded to Flux.Tracked.track(f, a, b).
Since TrackedArray is subtype of AbstractArray, i do not know, how to achieve that if none of those arguments are of type TrackedArray, the function should be dispatched normally, which if at least one of the is of type TrackedArray, it is forwarded to track.
I have ended up defining all four functions (in a loop), but I wonder if there is a neat solution. At the moment, I can also thing about using generated function as well.
Thanks for opinions.
