Subject: Re: Python from Matlab From: George Fazekas <gyorgy.fazekas@xxxxxxxx> Date: Fri, 22 Aug 2014 10:31:45 +0100 List-Archive:<http://lists.mcgill.ca/scripts/wa.exe?LIST=AUDITORY>wohoo that sounds fancy! It would be interesting to have an environment which really combines the two. Though Matlab has an interface that no other environment provides, I came to prefer something lighter for daily work, not to mention the better support for OO and external libraries in Python. Though not a direct solution to the questions below I highly recommend looking at iPython Notebook. You can seamlessly combine Python, R, Bash and whatever else through Magic extensions, passing variables between languages at will. Although plotting within iPython is almost as easy as in Matlab, I found plots generated by R much nicer and I frequently pass results from Python to R for plotting or do some stats that isn't available in Scipy. You can have code cells that are entirely written in R or just execute a single R function mixed in a Python script... Some basic examples: http://ipython.org/ipython-doc/dev/config/extensions/rmagic.html Cheers, George On 22 Aug 2014, at 09:55, Sebastian Ewert wrote: > Hi, > > the upcoming version of matlab has native python support (at least according to the beta changelog).

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. >> >> Alain >> >> >> >> On 21 Aug 2014, at 11:20, Marek Rudnicki <marek.rudnicki@xxxxxxxx> wrote: >> >>> Etienne Gaudrain <e.p.c.gaudrain@xxxxxxxx> writes: >>> >>>> Dear Marek, >>>> >>>> This looks very promising, I'm glad to finally see the first signs of a >>>> shift from Matlab to Python.
