Hello,
thanks to all who responded and have their input here.
I added a little code snippet to show the view and reshape:

Is this worth to go into the official docs?

Hi,
I've got two issues:
First, the following seems to cause a memory leak,
using numpy 1.3.0:
a = matrix(ones(1))
while True:
a += 0
This only seems to happen when a is a matrix rather
than an array, and when the short hand '+=' is used.
Second, I'm not sure whether that's a bug or

Thanks for the reply.
Yes never mind the second issue, I had myself confused there.
Any comments on the memory leak?

hi there,
I just installed the current head of numpy and built it. trying
python and then import numpy, and then CTRL-D to exit, all goes well.
But doing the same with a numpy.test() before CTRL-D ends up in :

Hm, upgrading scipy from 0.7.0 to 0.7.1 didn't do the trick for me (still
running numpy 1.3.0).
I'm not sure if I feel confident enough to use developer versions, but I'll
look into it.
Cheers

That the problem would be in Python is not so clear to me.

however, they are slower by at least a factor of 2 for my situation.
