Hello,

Please somebody help me !

I am really confused with all these void that I see everywhere.

The documentation says: PyObject * PyArray_SETITEM(PyObject * arr, void* itemptr, PyObject* obj)

I created a 1D array of doubles with PyArray_SimpleNew. Now I am in a loop of index i to feed my array with values. What should I give for itemptr ?

The pointer to your data indeed. For example, if you declare your item as:

double myitem

then, pass it as &myitem.
