This just shows that people use NumPy for lots of different things. I
myself have never understood what record arrays are for -- what's the
advantage of using NumPy if your data isn't made of numbers?
If you've ever used a dictionary instead of a list, then you have seen
the utility of named indices. I've got an example of labeled data in a
matrix, starting at slide 10 of
