Hi All,
I have been using Numpy for a while with great success. I left my
little project for a little while
(http://web.mit.edu/stardev/cluster/) and now some of my code is
broken.
I have some Numpy code to create graphs of activity on a cluster with
matplotlib. It ran just fine in July / August 2

Hi Folks
Is it possible some example how deal with strides with combinations, let see:
>>> from numpy import *
>>> import itertools
>>> dt = dtype('i,i,i')
>>> a = fromiter(itertools.combinations(range(10),3), dtype=dt, count=-1)
>>> a
array([(0, 1, 2), (0, 1, 3), (0, 1, 4), (0, 1, 5), (0, 1, 6),

you're welcome.

if you are adding a lot of rows one at a time, yes, you can have

Thank you for the quick response and Christopher's explanation on the
design background.
All my tables fit in-memory. I want to explore the data interactively and
relational database is does not provide me a lot of value.
I was rolling my own library before I come to numpy. Then I find numpy'

cool! There is a lot of other nifty- looking stuff in there too. The OP
should really take a look.
And maybe an appending function is in order, too.

Hello, I have been trying two methods for creating a rec array from my
data (or a structured array -- I'm still not completely clear on the
distinction). In terms of data, you can see what types they are,
basically simple (n,1) np.ndarrays. I had to reshape them to (n,1) to
get them to work with hs
