Ok, maybe can you print shape of the {rho} array as calculated my
matlab? I know that sum() in matlab sums over rows (i.e., the first
dimension), but I'm curious if it returns for an, say, (10x20) array
an (20,) array or an (1, 20) array.
And to Josef: cx is an 1d vector, so no. And Hmmm ... mos

Thanks and in fact, I already wasted quite some time on and your last version
will help me a lot. Unfortunately, I'm not a specialist at lattice Boltzmann
methods at all so I'm not able to answer your questions (my initial idea was to

Ok, so I send yet another version. Maybe Bruce is right, but I didn't
care, because we have fret enough. Now it not only computes
something, but also displays something :-(
Nicolas, maybe you can now waste some of your time with it? I was
curious, both to understand and to get it working, but I

Thanks a lot for the translation.
I think the "opp" relates to the opp array declared at the top and the
circshift can be made using numpy roll. I modified your translation to include
them.
The results should be something like

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
