Hi David,
Forgot to answer last week, I was under a fair bit of pressure time wise,
but thanks for your input. I sorted it all in the end and just in time, but
the main issue here was the change from numarray to numpy. Previously where
a typecode of 'f' was used in numarray, the calculation was pe

Yes, the memory argument explains why you would float32 data vs
float64 d
You can find PLS in pychem and MDP (Modular data processing)

Anyone want to help with improvements to fromfile() for text files?
See some notes from me about it on this list in the last month or so.

Hi all,
I'm trying to replace matlab with python in my daily work and I have
several problems now.
1) Which one should I use, numpy or scipy ? I found that numpy and
scipy have many overlap functions and modules, such as numpy.linalg
and scipy.linaly.
Maybe I should use numpy in some occasions a

Hi guys,
I am new to python, and still wondering around to solve a simple problem.
I have an array A, and want to save it to a binary data file with
'float64' and 'big-endian' specified. I searched online, but still don't
know how to do it. I appreciate your help!

Hello,
There have been a few updates to the 1.2.x branch that resolve some
issues with the last release candidate:
- a loadtxt regression: http://projects.scipy.org/scipy/numpy/changeset/5790
- a knownfailureif decorator was added:
http://projects.scipy.org/scipy/numpy/changeset/5792

If numpy is installed, then f2py will be too. On the windows environment,
there is a file called f2py.py that you can call from the command line. It
should be in the 'scripts' directory of your Python installation.
Try something like this:

Yeah, I memory wise it doesn't matter to sum to a double, but just
trying around it seems that the mixing of float and double is very slow
(at least on my comp) while if the starting array is already double
there is almost no difference for summing. Generally double precision
calculations should be

Just for my own benefit, I am curious about this.
I am running into problems because I need to archive the result (tuple)
returned by a numpy.where statement. Pickle does not seem to like to deal
with numpy scalars, and numpy's archiving functions (memmap) can't work on
the tuple that gets return

sure, but I'm a bit confused -- there is a tiny amount of memory

To All,
Has anyone worked with the F2PY generator? This is something that is
supposedly built within numpy and scipy. I was wondering if anyone has
had any issues with this environment?? It is important for my current
employment!!
