Your atlas is most likely broken. You will have to double-check how you
built
Hello,
I've encountered a segfault in numpy when trying to compute a dot
product for two arrays - see code below. The problem only seems to
occur when the arrays reach a certain size. I'm using Numpy version
1.3.0, installed via macports, on a 2.33 GHz Intel Core2 Duo Macbook
Pro running

Apologies - too quick to ask the list without thoroughly checking the online

Hello,
I am successfully using the new Pandas library for series and matrix analysis
using 2 dimensional arrays. I am using the "fromDict" method which works well,
and I am creating 2-dimensional arrays where each axis is indexed by FX
currency names. So for example pandas DataFrame called aa:

Hi, Wayne.
They're not nearly as structured, but for the time being
(indefinitely? unless a volunteer steps forward to build something for
us more closely resembling the GMI), you could use the numpy and scipy

Looks like 'sort' is not handling endianess of the column data
correctly. If you change the type of the floating point data to 'i2')])
In [141]: z.sort(order='num')
In [142]: z
Out[142]:
array([(255,), (0,), (256,), (1,), (258,)],
dtype=[('num', '>i2')])
In [143]: np.__version__
Out[143]

I was just looking at the (Win) Python documentation via the Help on
IDLE, and a Global Module Index. Does anything like that exist for
numpy, matplotlib, scipy?

I am having trouble sorting a structured array - in the example below, sorting
by the first column (col1) seems to work, but not sorting by the second column
(col2). Is this a bug?
I am using numpy svn r8071 on MacOS 10.6.
Thanks for any help,
