On a possibly connected but probably orthogonal note, this came
across my radar from the SWI list, an assembly language written
numerical library. I don’t know if it has array transposition but
somebody might care to wrap it with the FFI library in the future?
It does have Array Functions section and moving and copying things
but no explicit mention on that page. The source might reveal
more.
