 def tri(N, M=None, k=0, dtype=float):
         """ returns a N-by-M array where all the diagonals starting from
             lower left corner up to the k-th are all ones.
         """
         if M is None: M = N
         m = greater_equal(subtract.outer(arange(N), arange(M)),-k)
         if m.dtype != dtype:
             return m.astype(dtype)
         #else:
         #   return m

 tri(3, dtype=bool) will return None
 maybe should fix it by adding the block commented to the end of the code.
