Re: Python from Matlab

Alain,
It may be that Matlab will, in the future, make it possible for you to do this, but they will make the final switch virtually impossible. It is not in their best interest in supporting this move. Lots of people are frustrated with Matlab, especially the cell array problem and the poor support for ascii processing (which lead to the cell array issues 
in the first place).
It will be interesting to see how they make this final switch difficult. It is not obvious to me that they can block 
someone, other than a huge (10 year) stall.

Hi Marek,

I am looking for the opposite: an easy, efficient  and reliable way to call Python from Matlab.  My programming environment nowdays is matlab and I can't easily change.  The best course that I see is to implement new code in Python and call it from matlab, and make the switch to Python when Python code reaches critical mass.  I suspect many people are in a similar position.

Dear Marek,

This looks very promising, I'm glad to finally see the first signs of a
shift from Matlab to Python. Thanks a lot for sharing this!!

Dear Etienne

I'm glad you like it.

BTW, if you still have some MATLAB legacy code that you would like to
use in Python, then matlab_wrapper [1] could be helpful.  It allows you
to call MATLAB functions directly from Python environment (the MATLAB
process is started in the background), e.g.:

matlab.workspace.sin([0.1, 0.2, 0.3])


Cheers

Hi all,

we would like to announce *cochlea* -- a collection of inner ear
models in Python.  It was developed in the group of Werner Hemmert [1]
at the Technische Universit�t M�nchen.  After a few years of
development, we decided that it is stable and would like to contribute
it to the auditory community.



The main features of the package are:

   - simple to use (each model is implemented as a single Python
     function: sound in, spikes out)
   - fast (you can generate responses of hundreds or even thousands of
     nerve fibers)
   - all models have the same interface (easy to make comparisons and
     pick the one that best suits your needs)
   - up-to-date (recent models included)



Currently implemented models are:

   - Zilany, M. S., Bruce, I. C., & Carney, L. H. (2014). Updated
     parameters and expanded simulation options for a model of the
     auditory periphery. The Journal of the Acoustical Society of
     America, 135(1), 283-286.
   - Zilany, M. S., Bruce, I. C., Nelson, P. C., & Carney,
     L. H. (2009). A phenomenological model of the synapse between the
     inner hair cell and auditory nerve: long-term adaptation with
     power-law dynamics. The Journal of the Acoustical Society of
     America, 126(5), 2390-2412.
   - Holmberg, M. (2007). Speech Encoding in the Human Auditory
     Periphery: Modeling and Quantitative Assessment by Means of
     Automatic Speech Recognition. PhD thesis, Technical University
     Darmstadt.
   - MATLAB Auditory Periphery by Meddis et al. (external model, not
     implemented in the package, but easily accessible through
     matlab_wrapper).



We are really grateful to the authors of those models for allowing us
to use their code it in *cochlea*.  We release the package under the
GNU General Public License, so that you are free to copy, use and
modify the code.  We also encourage you to contribute back your
changes.


The code is distributed on GitHub [2] and the package/documentation
are hosted on the Python Package Index [3].  Check also our demo [4]!


If you would like to give a feedback, have questions or found some
problem, do not hesitate to email me or open an issue on GitHub [2].


Thank you and best regards
Marek Rudnicki
