Re: Octave_map and vectors

[Claudio Belotti]

That's exactly what I want but ...

test.cc: In function `class octave_value_list Ftest(const octave_value_list &, 
int)':
test.cc:23: no match for `octave_value & = octave_value_list &'
/usr/include/octave-2.0.17/octave/ov.h:170: candidates are: class octave_value 
& octave_value::operator =(const octave_value &)

the problem is retval(0) = array;

I've managed to return an octave_value_list but that's not what I want because 
I should know how many output are expected, and that's not my case.
