Hi all,
Is there a Python tool to read and write files in the
so-called universal format ?
I found a Matlab implementation
http://www.mathworks.com/matlabcentral/fileexchange/6395
Any pointer would be appreciated.
Thanks in advance

Hi,
as I mentioned in the past [1], we considered refactoring our VIGRA (an image
analysis library [2]) python bindings to be based on NumPy [3].
However, we have the problem that VIGRA uses Fortran-order indexing (i.e.
there's operator()(x, y) in C++), and this should of course be the same in

It seems to me that there are quite a few other functions that will
give
errors with 0-D arrays (apply_along/over_axis are two that come to
mind).
There is nothing to interpolate so I'm not surprised.
Hmm, I don't quite understand

Hello list,
I have a really simple newbie question: How can I mirror/flip a
numpy.ndarray? I.e. mirror switches the colums (leftmost becomes
rightmost and so on), flip changes the rows (top becomes bottom and so on)?
Kind regards,

Hello,
all these alternative mechanisms for initializing
arrays risk to break current code. Isn't it?
Then one would need to specify the data type
with a kw argument while with the current
implementation the second argument is the data type
irregardless of whether or not it is given with
the dtype
A humble suggestion--for the March meeting of the american physical society,
there is a roommate finder for splitting hotel rooms. This could be useful
in keeping expenses down for some. There should be a way to do it without
liability
Cheers,
