[GUFSC] mais uma razão para usar octave ao invés de matlab

[Ricardo Grutzmacher]

Retirado da lista de discussão do Octave:


| I find that octave is much better in scripts than matlab.  It is
| easier to fire off an octave from bash.  Doing so with matlab was
| always forced and required cludges last I tried (about 8 years ago).
| I presume that with the (imho stunningly awful) IDE that matlab uses
| and the whole windows way, that it is now worse than ever (someone
| chime in and prove me wrong -- I can't be bothered to find out since
| octave covers my needs).

Matlab can be started with the -nodesktop option, but it still takes
forever to check its license at start-up so it isn't suitable for
intensive use when scripting:

$ time echo 1+1 | octave -q
ans = 2

real    0m0.160s
user    0m0.120s
sys     0m0.040s
