[Numpy-discussion] reshaping array question

[Neal Becker]

I have an array of shape
(7, 24, 2, 1024)

I'd like an array of
(7, 24, 2048)

such that the elements on the last dimension are interleaving the elements 
from the 3rd dimension

[0,0,0,0] -> [0,0,0]
[0,0,1,0] -> [0,0,1]
[0,0,0,1] -> [0,0,2]
[0,0,1,1] -> [0,0,3]
...

What might be the simplest way to do this?

------------
A different question, suppose I just want to stack them

[0,0,0,0] -> [0,0,0]
[0,0,0,1] -> [0,0,1]
[0,0,0,2] -> [0,0,2]
...
[0,0,1,0] -> [0,0,1024]
[0,0,1,1] -> [0,0,1025]
[0,0,1,2] -> [0,0,1026]
...
