This is a NumPy question:
Say I have a loop that gives me a one dim array at a time. What would be
the most efficient way to accumulate it? Is the following a good way to do
it?
>>> from Numeric import *
>>> a = []
>>> for i in range(3): a.append(arange(5))
...
>>> array(a)
array([[0, 1, 2, 3, 4],
[0, 1, 2, 3, 4],
[0, 1, 2, 3, 4]])
What if I get a (1, n) shaped array at each step?
