I didn't change those manually, instead I wrote a bash script for this task,
see attachment. It can patch all octave-scripts at once.
But this is not perfect. In octave both ! and ~ allowed for negating,
in matlab just ~. This is not handled. I made no tests, since I
use my own signal processing and analysis toolbox.
There is a better converter:
http://octave.sourceforge.net/oct2mat/
but this also replaces functions calls, which may result in
octave-incompatible code.
It always has to be tested for compatibility. There are some
differences between Octave and Matlab, concerning
available commands and so called 'object oriented' functions.
Sometimes it works without modifications, sometimes not.
At least for my code, I try do avoid proprietary specials.
It's an ideological question (promoting Octave over Matlab),
whether we want the Octave-only style (which looks better indeed),
or a Matlab-compatible style.I don't want to judge about this,
since I didn't contribute to the gnuradio code (yet).
