Hello list,
I am not sure, if I understood everything of the discussion on the
named-axis-idea of numpy-arrays, since I am only a *user* of numpy. I
never subclassed the numpy-array-class ;-)
However, I have the need to store meta-information for my arrays. I do
this with a stand-alone class w

I'm looking forward to that -- you may have just saved me a bunch of coding!

Hi,
+1 on the idea but how will this work with other numpy methods?
suppose *arr* is a structured array with dtype:
[('name', 'S25'),
('height', float),
('age', int),
('gender', 'S8')
]
Would you be able to first define a list of columns such as
cols=['height', 'age']
arr[cols]
This woul

It sound kind of heavyweight to me. I tend to use lots of small arrays
(to represent an x,y point, for instance). There are enough performance
issues with that as it stands. Ma
