Thanks Fernando for the quick response. Today this is the 3rd time I am hitting an unsupported feature in the Python lands. 1-) No attribute docstrings 2-) Look this question: http://stackoverflow.com/questions/1458203/reading-a-float-from-string and 3rd is this. However I think I influenced to guys in our campus to take a look Python. One using Matlab-Simulink and C on collision-detection system design, the latter uses C to design a small scale embedded acquisition system for UAV platforms. He uses an ARM Cortex A8 processor powered Gumstix board<http://www.gumstix.com/store/catalog/product_info.php?cPath=31&products_id=228>. Xubuntu 9.04 runs on it. I saw Python 2.6.2 installed, however not sure how easy would that be to bring rest of the scipy stack into that machine. Besides, tomorrow there is going to be a Matlab seminar here http://www.mathworks.com/company/events/seminars/seminar39323.html It is about a SciPy advanced tutorial long. Many similar subjects I see there: *Speeding Up MATLAB Applications:Tips and Tricks for Writing Efficient Code *Topics include: • Understanding preallocation and vectorization • Addressing bottlenecks • Efficient indexing and manipulations • JIT • Interpreter • Mex *Brief Introduction to Parallel Computing with MATLAB *• Task parallel applications for faster processing • Data parallel applications for handling large data sets • Scheduling your programs to run I hope I will not kick out from the session by keep commenting oh that is possible in Python, oh this is too :) On Tue, Sep 22, 2009 at 12:18 AM, Fernando Perez <fpe...@gm...>wrote: > 2009年9月21日 Gökhan Sever <gok...@gm...>: > > > > It's a very late reply but I am wondering how to make these appear in the > Ipy dev loaded into the session but not visible to a whos listing? > > > > I don't think that's supported quite right now.
