Matrix transposition error

Two students in the course have independently called to my attention that there is an error in the transpose() method that I use in my programs in uke 3.
I have now corrected the programs and uploaded the corrected versions to the course web site.

Note that the error has essentially no influence on the TIMING results (albeit the matrix multiplications are wrong, they essentially take the same time as the correct multiplications).

Sorry for the error :-(

Sincerely,
Eric
