[Numpy-discussion] 3 comments on numarray documentation

[Edward C. Jones]

To access UInt8, etc,

     from numerictypes import *

Maybe mention this in 4.2.1.

-------

In 4.7

      Only one "..." is expanded in an index expression, so if one has a
      rank-5 array C, then C[...,0,...] is the same thing as
      C[:,:,:,0,:].

So an unexpanded "..." is treated as a ':'?

----------

In 5.1.1,

      >>> a = arange(5, type=Float64)
      >>> print a[::-1] * 1.2
      [ 4.8  3.6  2.4  1.2  0. ]
      >>> multiply(a[::-1], 1.2, a)
      >>> a
      array([ 4.8 ,  3.6 ,  2.4 ,  1.2,  0. ])

doesn't make the desired point. Try:

      >>> a = arange(5, type=Int32)
      >>> a
      [0 1 2 3 4]
      >>> print a[::-1] * 1.2
      [ 4.8  3.6  2.4  1.2  0. ]
      >>> multiply(a[::-1], 1.2, a)
      >>> a
      array([4 3 2 1 0])

Why does Python documentation always use the interpreter? I doubt if it 
is used much. Why not:

      a = arange(5, type=Int32)
      print a.type(), a
      b = a[::-1] * 1.2
      print b.type(), b
      numarray.multiply(a[::-1], 1.2, a)
      print a.type(), a
