While we're at it, why not an example of how the axis argument works:
>>> concatenate( (ones((1,3)), zeros((1,3))) )
array([[1, 1, 1],
[0, 0, 0]])
>>> concatenate( (ones((1,3)), zeros((1,3))), axis = 0 )
array([[1, 1, 1],
[0, 0, 0]])
>>> concatenate( (ones((1,3)), zeros((1,3))), axis = 1 )
array([[1, 1, 1, 0, 0, 0]])
I'm not sure I like this example, but it's a easy way to do a one liner.
