Hi Travis,
I looked through the recent commits to the datetime branch and, as I'm
working on cleaning up arraytypes I would appreciate it if you can merge up
your changes there as soon as possible to minimize conflicts. Also, this
change looks like a reversion of current trunk to something older:

As I posted in the past you can try this one liner:
"numpy.array(map(numpy.dot, a, b))
that works for matrix multiply if a, b are (n, 3, 3). "
This would also work if a is (n, 3, 3) and b is (n, 3
Thanks for sharing your ideas on this subject.
What I am most likely going to do is, do a test-drive for each mentioned

I use JabRef for quite some time. Very nice and cross-platform. Good
interoperability with LyX.
If you

That's giving me the same result:

Hi,
I'm trying to use F2PY on Mac OS 10.5 with G95, but I'm getting the
error "g95: unrecognized option '-shared'". I tried modifying the
NumPy code to use the correct "-dynamic" flag, rather than the
"-shared" flag. While that does allow for F2PY to successfully
execute, I get the error

The default finds both the g77 & gfortran compilers. The issue is that
the flags associated w/ both appear to be corrupted by the contents of
the intel fortran environmental variables (i.e. content matched, removal
of the intel system environmental variables made the problem go away),

Then how about known combinations of version numbers for g77/gcc,
python, and numpy? The gist would be to convey something that is known

Thanks a lot, now I have a quite fast program to compute Fractals :D.
Nevertheless, I want to comment some more doubts.
The speed at which some points tend to infinite is huge. Some points, after
10 steps, reach a NaN. This is not problem in my Mac Book, but in the PC the
speed is really poor when

There are no separate "text files" and "binary files". All files are
binary, some just contain text that in some cases represents an array of
numbers.
