A way to run a user-defined operation in the iteration about tensoroperations.jl

[Jutho]

I am planning to add a different macro, which really just creates explicit for loops around such an index expression. That would allow for much more flexible operations (e.g. custom functions etc). It would be less efficient for large tensors for the operations the @tensor macro can do. Something along the lines of einsum (see also #10 ).

@shashi - I believe what I have in Einsum.jl will work for you. The code is still a bit preliminary so be cautious and don't hesitate to open an issue if it fails.

See - https://github.com/ahwillia/Einsum.jl/blob/master/test/runtests.jl#L54

So @ahwillia , do you plan to register this as an independent package (or did you do so already)? If not, I would certainly be interested to a include it in TensorOperations.jl . I've had this is a planned feature in the Readme for a while already (see the very last paragraph).

[ahwillia]

Hmm. I think there are still changes/improvements I want to fiddle with.

What if I register it as a package and then you use reexport to add that functionality here? That might give us the most flexibility for now.

Does that agree with you? I can register it today.

@ahwillia thanks! that's useful.
