[SciPy-user] weave and numpy

[Sebastian Haase]

Hi,
if I pass a numpy array 'arr' as argument
a) how does the C code get arr.ndim ?
b) how does the C code get arr.shape[0],... ?
c) if the C code changes elements of arr, are those changes *on the original 
data* ? In other words, is weave.inline making a copy of arr ? 

I searched through 
http://projects.scipy.org/scipy/scipy/browser/trunk/Lib/weave/doc/tutorial.html?format=raw
but did not find a definite answer. From 
the 'array3d.py' example in weave in looks like Narr would contain the 
shape !? 

Thanks,
