Hi Isaac,
without proof, but I could imagine it's possible to implement a shear
operation via hyperslabs. If so, then hyperslabs could be used to
implement rotations:
e.g.
https://www.ocf.berkeley.edu/~fricke/projects/israel/paeth/rotation_by_shearing.html
To do a transpose, one would need a reflection in addition to rotation
(e.g. http://techieme.in/matrix-rotation/ ) , and I guess doing this
operation of a reflection is not possible via hyperslabs, so doing a
transpose is out of reach. Probably it would require to allow something
like a negative stride value...

Hi Quincy, I just was reading about point selections and was wondering
if that's the way we would go. Thanks for confirming!

for this. We hope we are wrong! It is possible to do this?
Hyperslabs won’t do this, but you could use a point
selection instead.
