The previous version of
setindex!
wasn't inverting the permutation, this fixes that issue. I also changed the tests to catch that issue, the previous version didn't catch it since the permutation was its own inverse.Additionally, I added some comments about how the
NestedPermutedDimsArrays
module could be rewritten using aPermutedDimsArray
wrapping aMappedArrays.MappedArray
, as mentioned in ITensor/BlockSparseArrays.jl#2. I tried it out and it mostly works but there would be a few issues to work through with that approach, probably best to keep it on the back burner for now and reassess later.
