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:

Thanks.

As ux 's shape is (1,lx,ly), ux(:,1,col) is equal to ux(1,1,col) which
is a vector with the elements [ux(1,1,2), ... ux(1,1,ly-1)].
Using : juste after the reshape seems a lit bit silly...
Except that python uses 0-based indexing and does not include the last
number in a slice, while
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
directory on http://projects.scipy.org/numpy/report/12 page for testing. The
following patch command

The patch files are placed in the top level numpy sandbox directory and
are in xml format rather than a diff file. I used save link as on the

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?
