Solely because I want to use the array with code that assumes it is
working with two-dimensional arrays but yet only performs operations
on the "outer" two-dimensional array that would be consi
How about
a = empty((5,7,4))
c = a[...,-1]

How can I do something
How can I do something like the following?
a = empty((5,7), dtype=<4 element array of floats>)
c = a[:,-1] # last column of 4 element arrays
a[0,0] = 2.0
print a[0,0]
[2. 2. 2. 2.]
a[1,0] = 3.0
a[0,1] = a[0,0] * a[1,0]
print a[0,1]
[6. 6. 6. 6.]
etc.
As always, thanks for the help!
Alex
