FA-98829 / Tensor stride and reshape semantics / Member archive
Tensor views: stepped slice multiplies stride · case 04
stepped slice multiplies stride.
Case contract
Positive-step slice length is ceil(max(0,stop-start)/step), offset advances by start stride, new stride multiplies by step.
Why this case matters
Dense tensor views rely on consistent logical coordinates and physical storage addresses.
One recorded failure
Sample boundary fixtureThis sample comes from the broken implementation of a controlled reproducer.
| Boundary fixture | Actual | Expected | Outcome |
|---|---|---|---|
| odd length | [[7], [4], 6] | [[4], [4], 6] | Failed |
