Oh, this is very strange. Matrix transposition is in multik-core and isn't tied to platforms or android versions.

Does the code differ from the version?

What is the size of the ndarrays?

Transposition, as far as I remember, is a view/lazy operation. We don't directly copy the data itself, we only change its representation. Copying occurs if data consistency is required for a subsequent operation.
