Re: How does Octave shine?

[Peter Cloetens]

Hi,
We moved most of our processing for tomographic imaging from matlab to octave. 
The main benefits that I feel are:
1) we are no longer stuck because of unavailable licenses (we used floating 
matlab licenses)
2) octave is sometimes 20-30% faster for processing involving lots of FFT's 
(Fourier Optics, ...)
3) we have many cases where we need stupid parallelization. with Condor for job 
scheduling + octave we can use tens of CPU's
4) for display and interaction with images we use now ImageJ and octave can get 
some of the results. so we got rid of matlab's lousy image tools.
5) in the details, coding in Octave leaves more freedom (! or ~, # or %, " or 
',...) and it is closer to other languages (some of the matlab weird 
specificities are gone)
6) matlab is clearly more and more a windoze program that happens to be 
available for linux/unix. octave integrates much better with linux and batch 
processing, an important advantage for us at least.
In my experience it is not very difficult to convince a beginner to use either 
octave or matlab, to convince long-term matlab users can be more difficult...
Good luck,
Peter
