matlab combatibillity of v3.2

[WMennerich]

Hello,
First, I want to congratulate to the new version 3.2, which seems to be a big step.
I just tried the Octave MinGW 3.2 and found an incompatibility to Matlab:

In matlab you can have

>switch travellingDirection

In octave, this does not work, you need {'east' , 'west'} instead of {'east' 'west'}

[ I mean the colon between 'east' and 'west' ]


I will solve this for me by changing my user code, so see this more as an information.


Another thing is the matlab 'dbstop if error' comand. Octave 3.2 (MinGW) gives an error:
>error: add_breakpoint: unable to find the function requested
I dont now whether this is not yet implemented or just a bug.

Best Regards, Wolfgang

I checked in the following change.

  http://hg.savannah.gnu.org/hgweb/octave/rev/29563379fa9b

Jaroslav, since this used to work in 3.0.x, I think this patch should
be applied to the 3.2.x release branch.

Debugging on error conditions is implemented, but someone needs to fix
the dbstop command to parse its arguments in a Matlab compatible way.
I'd certainly consider a patch.

For now, you can use

  debug_on_error (true);

instead.

Done.
