  The wrappers can provide faster special case calculations for lower dimension vectors and matrices. This would increase speed in a lot of applications.

  1/ Do you have an idea of the performance gain this brings (for a particular system, I know. Do we have a KF test that uses 2D matrices somewhere at this point) 2/ Isn't this something we should try and get in upstream implementations. After all, BFL wants to provide wrappers and leave matrix functionality in matrix libraries (Herman, this must sound like good sixties music in your ears :-) 3/ Since it's committed, you probably could change the status to resolved (unless you were anticipating annoying remarks from retired phd students, that is :-)
