Re: [Numpy-discussion] Problem in swig

20 May 2010

      Hi

Thanks for all your help!

I found the "strange" result was caused by my algorithm(CUDA).

The swig part is very ok:)

I tried the following:
%module example
%{
#define SWIG_FILE_WITH_INIT
//#include "example.h"
%}
%include "numpy.i"
%init %{
    import_array();
%}
%apply (float* INPLACE_ARRAY1, int DIM1) {(float *a, int na), (float
*b, int nb)};
%inline
{
  void update_incident_field(int k, float *a, int na, float *b, int nb)
  {
    for (i=0; i
$ swig -python example.i
and the resulting example_wrap.c file looks OK for me.  What strange
output did you get?

I want to pass 1 integer and 2 numpy array into the C function as
followings:
void update_incident_field(int k, float *a, int na, float *b, int
nb) {
for (i=0; i
But I don't know how to write the interface code (***.i)
Can someone help me?
Thanks!
The swig interface code I written(did't work, strange output)
%module example
%{
#define SWIG_FILE_WITH_INIT
#include "example.h"
%}
%include "numpy.i"
%init %{
    import_array();
%}
%apply (float* INPLACE_ARRAY1, int DIM1) {(float *a, int na), (float
*b, int nb)};
%include "example.h"
