Hello All:
Well, I recently managed to get some small FEM code to work using
NumPy and some .so modules I created from Fortran90 routines via f2py.
Anyways, my Prof was impressed with f2py but had a simple question
that I'm afriad I didn't precisely know the answer to.
The question is this:

I wanted to use rec.fromrecords so that the interface is consistent.
For example, suppose I have a list comprehension that generates the
variable "recs". Sometimes the list compreh

Hi,
I am trying to create record arrays using the numpy.rec.fromrecords.
This function works just fine, however I am having a little trouble
using it to create empty record arrays. If the array I start off with
is empty and I have provided a dtype (or the names and the formats),
then I expect rec.
Thank you everybody for your replies.

It depends what it means -- and this is not a question of Pythonic --
maybe Numpythonic?
Numpy is an n-d array package -- NOT a matrix package (

Hello Everyone,
Another behavior we might consider changing for 1.0.2 that I believe is
somewhat related in theme is the default type used in computations like
the mean() method.
This is best illustrated with the following example:

You can also create an array from a Python list, data in a file, another
array or a memory mapping. In these c

Dear All
I'm happy and proud to announce that a repository for free chemometric
software (in particular Python oriented) has started.
at www.chemometrics.it
Some time ago I've sent an email to the ICS asking if anybody knows
the esistence of a python repository for chemometrics,
I had a positi
