From the svn log it looks like the tests are intended to fail? However
I would prefer tests that are designed only to fail when problems
occur. Otherwise we end up with problems with our automatic build and
test scripts.
Thanks,

Because that's just what a buffer= argument *is*. It is not a place
for presenting the starting pointer to exotically-strided memory. Use
__array_interface__s to describe the full range of representable
memory. See below.
Aha! Is this stuff documented

I was about a week ahead of you. See numpy/lib/stride_tricks.py in the trunk.
Robert, this is fantastic! I think people are going to enjoy your
talk at SciPy'08. If you want, we could also tutor this in the
advanced NumPy session.
Cheers

Thanks for the precise explanation that make things clearer. In fact,
the example I gave was mainly to illustrate my question in the quickest
way.
Concerning the dtype argument during array creation, I thought it was
here for somehow controlling the type of array elements. For example, if

within numpy is going to be fairly cumbersome. But I think there are
better algorithms you could try:

Anne Archibald already responded:
