Description
What is your question?
Hello!
Would there be easy ways to get a slice of the Tensor while keeping the dimension?
I have a tensor with shape (16, 4, 16)
When doing
for(int idx = 0; idx < size<1>(tensor); ++idx) {
slice = tensor(_, idx, _)...
}
This generates slice with shape (16, 16).
Would it be possible to get (16, 1, 16) instead?
Thanks!

Research direction
Start with the tensor slicing expression shown in the issue and inspect the CUTLASS tensor-view and slicing APIs to determine whether a singleton dimension can be preserved. Confirm whether the requested (16, 1, 16) shape is supported; if not, identify the relevant API limitation and document the result or proposed change.
