Any update on a transpose function?

There is a transpose function in Explorer which I think is a better fit than the standard library. Lists of lists are just flat not an efficient structure on which to do matrix operations, and I don’t think it makes sense to build a set of functions around using them for that purpose.

So we need an external dependence to do something as trivial as rotate a list of list? I am not asking to handle matrix in the standard library, I am asking for something for List and Enum.

Serious question: when are you rotating a list of lists in Elixir? Advent of code and other puzzles don’t count.

Explorer and Nx were created by the creators of elixir explicitly to do number crunching operations in the language. Given the extra dependencies involved and the relatively specialized area of work for those operations within the general use cases of the language.

Isn‘t Enum.zip_with(nested, & &1) what you‘re looking for?

Yes it is working. Note that what I am looking for is not quite an implementation of transpose but a way to add transpose to the library. This goal is not have to write it each time

transpose = fn nested -> Enum.zip_with(nested, & &1) end

Last time it was to handle data send by a client in day job. It was not in Elixir. So the answer to " Any update on a transpose function?" would be “none because not enough people ask for it” right?

I don’t speak for Ben but IMO the answer would be more along the lines of: “We deem this a more specialized functionality and as such we will not put it in the standard library and into a dedicated number-crunching library instead”.

alright. thank you
