Improve reordering tests #241

Closed alankao64 closed 4 years ago

Adding more tests cases for reordering of tensor indices.

alankao64 commented 4 years ago

Interesting...the visual representation of this contradicts my understanding of how left-reorder works. How is a left-reorder able to manipulate an index in the rightmost region?

From my understanding of what @benjaminvillalonga said, the left-reorder will check up to 8 indices from the left and if it can complete the reordering by doing a left move with those indices then it will do so.

Huh. In that case, I guess leave the test as-is, but update the comment with this explanation + updated section boundaries.
