ANN: SfePy-00.50.00

I am pleased announce the release of SfePy 00.50.00.

SfePy is a finite element analysis software in Python, based primarily
on Numpy and SciPy.

Mailing lists, issue tracking, mercurial repository: http://sfepy.org
Home page: http://sfepy.kme.zcu.cz

People who contributed to this release: Ondrej Certik, Ryan Krauss, 
Vladimir Lukes.

Major improvements:
- finite strain elasticity: neo-Hookean, Mooney-Rivlin materials in the 
total Lagrangian (TL) formulation
- solving problems in complex numbers
- generalized equations to allow linear combination of terms
- run-time type of state term arguments
- refactoring to follow Python coding style guidelines
- new terms

Is it ok to start a signal/speech toolbox in scikits ?

Hi,

    I know there is no formal process, but just wanted to check whether
anyone would be against starting a speech/signal toolbox in scikits. The
idea is to provide things which where in my sandbox before, but are
relatively general (lpc, music and other high resolution methods
available in matlab signal toolbox), as well as more speech oriented
stuff (mfcc, etc...). The code would be as much BSD as possible, so that
some of it may be included in scipy later if deemed useful.

cheers,

David

That sounds great.  Once you get started, we can take a closer look
and give you some feedback.

Thanks,

scipy.cluster.distance.yule print statement

There's a print statement in scipy/cluster/distance.py:yule that
creates an enormous amount of output when the SciPy test suite is run.
 Can that be commented out or removed?

Re: numpy.distuils question

Uwe,

I'm attaching an example of setup.py i have that does what you want.

I have the strucutre:
setup.py
  Lib/
    __init__.py
    ...python files ....
  Src/
     ..fortran or C files ...

Hope this helps.
C.

Note that I also have a .pyf file just to make the i/o to f2py a bit 
cleaner but it is not necessary

C.
