I was trying to find out what the "helpful" message
"TypeError: expected a readable buffer object" means
and it seems genfromtxt has problems identifying long integers (at
least on Windows 32)
>>> np.array(416068,int)
Traceback (most recent call last):
File "", line 1, in
np.array(416
Francesc Altet once provided an example that for integer
division, numpy uses the C99 rule: round towards 0.
This is different than Python's rule for integer division:
round towards negative infinity.
But I cannot reproduce his example. (NumPy 1.3.)
Did this behavior change at some point?
Thanks,

That gives
I have installed latest numpy from svn on ubuntu karmic(9.10) and compiled
the code in my sand box. I downloaded two patches
(test_umath_complex.py.patch, build_clib.py.patch) from the review patch

Thanks.
I agree that the use of ':' is a bit weird.

Hello,
I'm trying to translate a small matlab program for the simulation in a 2D flow
in a channel past a cylinder and since I do not have matlab access, I would
like to know if someone can help me, especially on array indexing. The matlab
source code is available at: http://www.lbmethod.org/o
