Well, you will definitely want to use numpy arrays instead of lists or the
standard library's arrays to c

Hello,
I suggest that you might take a look at how other people solved the
same problems. The great example is path.c insi

Brian and Diez:
First of all, thanks for the advice.
Brian:
I have installed NumPy and SciPy, but I can't seem to find a wavelet
transform there.
The main point of this was more to learn C wrapping than to actually
get a calculation done. I will probably be starting a PhD soon, doing
real
SWIG is a program that automatically generates code to interface
Python (and many other languages) with C/C++. If you plan to create
lasting software libraries to be accessed from Python and C it is
quite a robust way to do so. Essentially, you feed it header files,
compile your code and the code
Hi, and thanks.
However, being a newbie, I now have to ask: What is SWIG? I have heard
the name before, but haven't understood what it is, why I need it, or
similar. Could you please supply some hints?

We use the following SWIG (www.swig.org) typemap to perform such operations:
%typemap(in) (int argc, char **argv) {
if (!PySequence_Check($input)) {
PyErr_SetString(PyExc_ValueError,"Expected a sequence");
return NULL;
}
$1 = PySequence_Length($input);
$2 = (char**)alloca($1*sizeof
Hello etc.
I am a "scientific" user of Python, and hence have to write some
performance critical algorithms. Right now, I am learning Python, so
this is a "newbie" question.
I would like to wrap some heavy C functions inside Python,
specifically a wavelet transform. I am beginning to bec
