Hi numpy people,
I have a problem with array broadcasting for object arrays and list. I
would like to create a numpy array containing empty lists (initially -
I will append to them later):

Is it possible to broadcast a list to all elements of a numpy
Thanks Bill, it helps me a lot ! My function works fine now.
But I encounter an other problem. This time with a NumPy array of 2
dimensions.
Here is the function I want to use :
//
double matSum(double** mat, int n, int m){
int i,j;
double sum = 0.0;

Slightly simpler would be:

Dear David,
Without going into the inherent benefits of the MSI (Microsoft
Installer) architecture over other EXE setup formats, its main advantage is
that MSI packages can be added to Group Policy Objects in Active Directory

Kevin,
In this instance, the best thing is to write a wrapper function that
calls your matSum() function, and takes a double* rather than a
double**. You can %ignore the original function and %rename the
wrapper so that the python interface gets the name you want.

Hi all,
I'm having a seg fault error from numpy.rec.fromarrays.

Then I attempt
A = numpy.rec.fromarrays(L,names = ['Aggregates','__color__'])
So what happens when you set the dtype here?
Since you have variable lengths of strings, numpy probably has guessed
incorrectly. I would also check that Col1 and Col2 are what you expect,

Hello,
Sorry for any overlap, as I've been referred here from the scipi-dev

I was reading through the Summer of Code ideas and I'm terribly
interested in date/time proposal
Ciao Marty,
Great idea indeed ! However, I'd really like to have an easy way to
plug the suggested dtype w/ the existing Date class from the
scikits.timeseries package (Date is implemented in C, you can find the
sources through the link on http://pytseries.sourceforge.net). I agree

Yes, it would - but then people would complain about numpy being slow,

Thanks for the input, guys. I'll be looking into the
scikits.timeseries package before submitting an application.
was it the intent that these new data types should be implemented at the
C/cython level?
That's fine with me. I've got plenty of experience in C++, and I've
