Re: [Swig-user] receive bidimensional array from C in Python using SWIG

[Mistervanhalen <mis...@gm...>]

Thank you for your answer.
My C prototype function is

void fct(int a,int **matrix)
And I want to get matrix in python

-->test.i
%module libMAT

extern void fct(int a, int **OUTPUT);

Is it right ?

In python
import libMAT
#import numpy

libMAT.fct(2)  -> doesn't work !
How do allocation ?
Do you have an test.i to get ** matrix exemple and in python after ?
I want to get matrix in an array in Python
I tried to read swig doc but it's hard to understand.
THank you.
