[IPOL discuss] MATLAB demos

[Jacques Froment]

Dear Miguel,

Exactly, my suggestion is basically to allow only Matlab toolboxes that
have the same signature and behavior as those available on Octave-Forge.
More precisely, since all functions of a given Matlab toolbox may not
be implemented in the corresponding Octave-Forge package, I mean to
allow only functions implemented in Octave-Forge that give the same
results than the ones in Matlab toolboxes.

I believe that this compatibility may be checked almost automatically at
the editing step by checking that the source code gives the same outputs
(within a given numerical accuracy) running on Octave.

I agree that this compatibility requirement would add a bit of work for
authors and editors, but it would be a "political" statement in favor of
free and open source softwares and it would not disadvantage labs that
do not have Matlab license (which is rather frequent outside the US and
elsewhere, outside major labs).

Best,
Jacques.
