Sparse tensor: transpose swaps shape but leaves coordinates unchanged · case 04
transpose swaps shape but leaves coordinates unchanged.
Case contract
Transpose COO entries by swapping each row and column coordinate, then sort row-major.
Why this case matters
A small offline sparse-array operation has explicit coordinate and storage semantics.
One recorded failure
Sample boundary fixtureThis sample comes from the broken implementation of a controlled reproducer.
| Boundary fixture | Actual | Expected | Outcome |
|---|---|---|---|
| off diagonal | [[0, 7, 7], [5, 1, 3]] | [[1, 5, 3], [7, 0, 7]] | Failed |
