Hi,

I just think about another silimar problem.

The code is here:
-------------------------------------
> >> a = array(range(10))
> >> a
array([0, 1, 2, 3, 4, 5, 6, 7, 8, 9])
> >> a[4,6]
Traceback (most recent call last):
File "<interactive input> ", line 1, in ?
IndexError: invalid index
> >> a.shape = 1,10
> >> a
array([[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]])
> >> a[0,[4,6]]
array([4, 6])
> >> a[:,[4,6]]
array([[4, 6]])
-------------------------------------------
If I only want to index No 4 and No 6 in a 1-D array a. Using a[4,6] is
obviously wrong.
Under this situation, do I have to shape it to a 2-D 1-by-10 array as
shown above?
Then use a[0,[4,6]] to index them?
