Hi everyone,

I would like to ask your advice how I can use NumPy to wrap my existing
C++ library with 2-dimensional arrays. I am wrapping the library with
swig and I have the typemap function declaration. But now I

Hi,
In fact, it's not that complicated. You may know the way how copying a

(http://matt.eifelle.com/2008/01/04/transforming-a-c-vector-into-a-numpy-array/).
You will have to copy your data, it is the safest way to ensure that
the data is always valid.

we recently had a discussion about being able to do some common things
like reductions and binary operations on recarrays, and there didn't
seem to be much consensus on it being needed in the core of numpy.
Since we do actually need this quite pressingly for everyday tasks,
we wrote a
Hi Matthieu,
Thanks for your quick reply! I did not find this page earlier. I have
studied the first page and now I realize again that all my efforts so
far (last few days) have crashed on the lack of calling import_array().
Do you have a suggestion for calling import_array() as well?
Hi,
I'm sorry, I guess I did not search properly before For the record,
I solved my import_array() question: just need to add
%init %{
import_array();
%}
and the typemap for the std::vectordouble works ok. Thanks for that!
Now the rest...
Thanks

Yes, there is so much information everywhere. And it's hard to make the
first steps.
For the std::vector[], I suggest you convert it to a single vector,
as the data inside this array is not contiguous

Hello,
I've been using record arrays to create arrays with different types
and since I'm doing a lot of computation on each of the different
fields, the default memory layout does not serve my computations.
Ideally, I would like to have record arrays where each field is a
contiguous

Does Numpy use Python's standard math library when calculating
elementary functions such as exp(x) and acos(x)? Also, what is the
internal library of Numpy and Python's standard math library? Are they
platform independent?

What are some differences between arrays and matrices using the Numpy
library? When would one want to use arrays instead of matrices and vice

Matrices are 2D array with some additional properties that make them more handy
for linear algebra. For instance
mat1*mat2
is a matrix multiplication, while
arr1*arr2
is an element by element multiplication. However
np.dot(arr1, arr2)
is a matrix multiplication between two arrays.

Thanks for the quick answer. It makes sense.
I will have to find some other way to do it then.

That would indeed be ideal. But I should add that I was not proposing

There is no such path right now. Numpy and Scipy are only available for
Python 2.x (with x = 4). As very large C extensions,
