Ways of performing Accumulation with Dynamic Arrays
This has been a great thread! Thanks to all the contributors. We just announced a new wave of lambda functions that I think will greatly help these scenarios. In particular, REDUCE, SCAN, BYROW and BYCOL.
Thanks for sharing, I will be able to test when LAMBDA goes live - whenever that will be... I'm not familiar with the details but this appears to be similar to the pipelined binary tree section of Prefix sum - Wikipedia - all the more impressive that you have come up with this type of implementation independently.
As discussed elsewhere, I hope we get capability for running totals built in soon - functions like map, reduce, fold and scan have been mentioned in a recent MS research podcast.
lori_mI tried to ask about map/fold/etc. timing as part of the YouTube livestream I linked to up-thread, however the moderator didn't include part 2 of my question, only the LAMBDA Playground/Editor was addressed. Perhaps if Andy replies to me about LAMBDA playground I can ask about the timing of those as well.
