[Matrix-SIG] rotater?

[Yoon, Hoon (CICG - NY Program Trading)]

Tim,

  Thanks much for your answer. It partially answer my Q. Unfortunately, this
still means I need to loop over axis as you have said. Probably C extension
time.
  Just few things that one expects when converting from one lang to another.
Most stuff are easy, but few things are still easier on the old lang.
