RE: Data acquisition?

[Laurence Lurio]

Dear Matthias,

I haven't actually done this in octave, so I am just guessing here.  If you
could write c-code to control your device (or are supplied with a c-library
by your vendor) then perhaps you can try to link this to octave using
mkoctfile. Alternately, if your control software exposes objects then you
might be able to do something similar and communicate with your running
software from octave.  While python would certainly do the trick I can
imagine cases where you might want real time math processing of your data,
which would be much easier through octave.

While Octave is very good at numerical analysis, it is not a complete
programming language with a large library for example for connexion.

I would suggest that you have a look at python and its libraries as a
way to manage your apparatus.

First http://pyserial.wiki.sourceforge.net/pySerial and then many
others. Python also contains many libraries to manipulate data easily
"à la octave way" (see scipy, numpy and pylab).

Nicolas
